Liquid is a __________ of matter
Explanation
The correct answer is "state" because liquid is one of the three states of matter, along with solid and gas. In the liquid state, the molecules are close together but can still move freely, allowing the substance to take the shape of its container.
2.
Syrup, honey, liquid soap, oil and paint are all ____________
Explanation
The given answer is correct because all the mentioned substances - syrup, honey, liquid soap, oil, and paint - are in a liquid state. Liquids are substances that have a definite volume but no definite shape, and they can flow and take the shape of their container.
3.
Liquids take the ____ of their container.
Explanation
Liquids have the ability to conform to the shape of their container. This is because the particles in a liquid are not tightly packed together and have more freedom to move than in a solid. As a result, they can flow and take on the shape of the container they are in.
4.
Liquids that flow quickly are___________, like water, juice and milk.
Explanation
Liquids that flow quickly are thin because thin liquids have a low viscosity, meaning they have a low resistance to flow. Water, juice, and milk are examples of liquids that have a low viscosity and flow easily.
5.
Liquids that flow slowly are __________, like honey, paint and glue.
Explanation
Liquids that flow slowly are referred to as "thick". This term is used to describe substances like honey, paint, and glue, which have a high viscosity and do not easily pour or spread. The thickness of these liquids makes them more resistant to flow, resulting in a slower movement compared to thinner liquids.
6.
The amount of ____ a liquid takes up is called its volume.
Explanation
The amount of space a liquid takes up is called its volume. In other words, volume refers to the physical extent or size of a liquid. It represents the three-dimensional capacity or amount of room occupied by the liquid.
7.
Tools used to measure volume of the liquids: measuring ________, graduated cylinder, spoon or beaker.
Explanation
The answer "cup" is correct because it is one of the tools commonly used to measure the volume of liquids. Cups are often used in cooking and baking to measure liquid ingredients. They come in various sizes and have markings on the side to indicate different volume measurements. While other tools like graduated cylinders, spoons, and beakers can also be used to measure volume, a cup is a simple and convenient option for everyday use.
8.
The units of volume are milliliters (________) or liters (________).
Explanation
The units of volume can be measured in milliliters (mL) or liters (L). Milliliters are used for smaller volumes, while liters are used for larger volumes. Both units are commonly used in scientific and everyday measurements.
9.
The volume of the same amount of liquid does __________ from container to container
Explanation
The volume of liquid remains constant and does not change when it is transferred from one container to another. This is because the volume of a substance is a physical property that is independent of the container it is placed in. Therefore, regardless of the shape or size of the container, the amount of liquid will always occupy the same volume.
10.
When liquid is poured into container, the shape of the liquid ___________.but its volume stays the __________
Explanation
When liquid is poured into a container, the shape of the liquid changes to fit the shape of the container. However, the volume of the liquid remains the same. This is because the volume of a substance is a measure of the amount of space it occupies, and pouring it into a different container does not change the amount of liquid present. The shape of the liquid can vary depending on the shape of the container, but the overall volume remains constant.
11.
Matter can have three ___________: gas like air, liquid like water and solid like stones.
Explanation
Matter can exist in three different forms or states: gas, liquid, and solid. These states are determined by the arrangement and movement of particles within the substance. In the gas state, particles are widely spaced and move freely. In the liquid state, particles are closer together and can move past one another. In the solid state, particles are tightly packed and vibrate in fixed positions. These states of matter have distinct physical properties and behaviors, which are important in understanding the behavior and characteristics of different substances.
12.
A _________ is state of matter that has no definite shape or size like helium or neon.
Explanation
A gas is a state of matter that does not have a definite shape or size, such as helium or neon. Gases are composed of particles that are widely separated and move freely, filling the space available to them. They can be compressed or expanded easily and have low density compared to solids and liquids. Gases also have the ability to diffuse and mix with other gases.
13.
Gas occupies all __________ it can ( sine gas has no definite size). Air freshener in a room can be smelled anywhere in the room.
Explanation
Gas molecules are not bound by a definite size or shape, allowing them to spread out and occupy all available space. This is why air freshener, which is in the form of a gas, can be smelled anywhere in a room. The molecules of the air freshener disperse throughout the room, filling the space and reaching our noses no matter where we are.
14.
A gas takes the shape of its container e.g the shape of the helium gas in a star-shaped balloon is a ___________ shape.
Explanation
The gas takes the shape of its container, meaning it will fill the available space regardless of the shape of the container. In this case, the helium gas in a star-shaped balloon will take on the shape of the balloon, which is a star shape.
15.
Air is made up of ____________
Explanation
Air is made up of gases such as nitrogen, oxygen, carbon dioxide, and other trace gases. These gases are essential for supporting life on Earth. Nitrogen makes up the majority of the atmosphere, while oxygen is vital for respiration. Carbon dioxide plays a role in the Earth's climate system. Other gases like argon, helium, and methane are present in smaller amounts. Together, these gases create the composition of air that we breathe.
16.
The state of matter of the air in a balloon or ball is __________
Explanation
The state of matter of the air in a balloon or ball is gas because air is composed of various gases such as nitrogen, oxygen, carbon dioxide, and other trace gases. In a balloon or ball, the air molecules are not tightly packed together like in a solid or liquid, but instead, they are spread out and move freely. This allows the air to fill the entire volume of the balloon or ball, making it a gas.
17.
Temperature tells us how warm or _______ an object its.
Explanation
Temperature tells us how warm or cold an object is.
18.
We measure temperature ____________ a thermometer .
Explanation
The word "using" indicates the method or tool that is employed to measure temperature. In this case, a thermometer is the specific tool that is used to measure temperature.
19.
Units of temperature are ________ Celsius or degrees Fahrenheit.
Explanation
The units of temperature can be expressed as either Celsius or degrees Fahrenheit.
20.
Two scales found on a thermometer are _______ and Fahrenheit.
Explanation
The two scales found on a thermometer are Celsius and Fahrenheit. These scales are used to measure temperature. Celsius is a metric scale commonly used in most countries around the world, while Fahrenheit is primarily used in the United States. Both scales have different reference points for freezing and boiling points of water, with Celsius having 0 degrees as the freezing point and 100 degrees as the boiling point, and Fahrenheit having 32 degrees as the freezing point and 212 degrees as the boiling point.
21.
The way along which a skater or object moves is called its ___________
Explanation
The term "path" refers to the route or trajectory that a skater or object follows while in motion. It represents the specific direction and shape of the movement, providing a visual representation of the course taken. By using the word "path," it emphasizes the continuous nature of the movement rather than just a single point in space.
22.
A __________ is a round and round movement
Explanation
A spin is a circular movement that repeats itself continuously.
23.
A pinwheel and a top move _________ and round.
Explanation
The word "round" is used to describe the movement of both a pinwheel and a top. It implies that both objects move in a circular or rotating motion.
24.
A zigzag motion looks like the letter ___________
Explanation
A zigzag motion looks like the letter Z because it consists of a series of sharp, diagonal lines that change direction repeatedly. The letter Z also has a similar shape, with two diagonal lines that intersect at a point, forming a zigzag pattern.
25.
To ________ means to go forward and backward ( back and forth ).
26.
The path made by the skier is a __________
Explanation
The path made by the skier is described as "zigzag." This term refers to a pattern or shape that consists of a series of sharp turns or angles in alternating directions. In the context of skiing, it suggests that the skier's path was not a straight line but rather a series of back-and-forth movements. This term accurately captures the visual image of the skier's path and implies a dynamic and energetic movement.
27.
A seesaw moves up and ___________
Explanation
The seesaw moves up and down because it is designed to pivot on a central point. When one side of the seesaw goes up, the other side goes down due to the principle of leverage. This allows for an alternating motion, creating the characteristic up and down movement of a seesaw.
28.
_______________ tells how fast or slow something moves
Explanation
Speed is a measurement that determines the rate at which an object moves. It quantifies the swiftness or slowness of an object's motion, indicating the distance covered per unit of time. Speed is a fundamental concept in physics and is commonly used in various fields such as sports, engineering, and transportation to evaluate and compare the velocities of different objects or systems.
29.
A high- speed train moves ________. A snail moves slowly.
Explanation
A high-speed train moves fast, while a snail moves slowly.
30.
Where an object, is its ____________.
Explanation
The answer "position" is correct because an object's position refers to its location or placement in space. It indicates where the object is situated relative to a reference point or coordinate system. The position of an object can be described using coordinates, such as latitude and longitude on Earth, or x, y, and z coordinates in three-dimensional space. Knowing the position of an object is essential for understanding its spatial relationships and for navigation or tracking purposes.
31.
When an object moves it ______________ its position.
Explanation
When an object moves, it changes its position.
