1.
Which of the following is a solid?
Correct Answer
B. Roller Coaster
Explanation
Solid is a state of matter that has a definite shape, volume and cannot be compressed. In this case, roller coaster has a definite shape and definite volume so it is a solid.
2.
What is ice?
Correct Answer
A. Soild
Explanation
Solid is a state of matter that has a definite shape, volume and cannot be compressed. Liquid has a no definite shape, has definite volume and cannot be compressed. Gas has no definite shape, volume and can be compressed. In this case, ice has a definite shape and volume. So it is a solid.
3.
What are the three states of matter?
Correct Answer
C. Solid, liquid, gas
Explanation
The different states of matter are solid, liquid and gas. Water is an example of liquid and air is an examples of gas.
4.
Which states of matter can be compressed?
Correct Answer
C. Gas
Explanation
Solid is a state of matter that has a definite shape, volume and cannot be compressed. Liquid has a no definite shape, has definite volume and cannot be compressed. Gas has no definite shape, volume and can be compressed.
5.
Which group of substances fit the description of "they have definite volume"?
Correct Answer
A. Spoon, plate, honey
Explanation
Solid is a state of matter that has a definite shape, volume and cannot be compressed. Liquid has a no definite shape, has definite volume and cannot be compressed. Gas has no definite shape, volume and can be compressed.In this case, only examples of solid and liquid have definite volume.
6.
If the shape of something changes when it is placed in different containers, it cannot be a _____________.
Correct Answer
solid
Explanation
The given answer is solid because solids have a fixed shape that does not change when placed in different containers. Solids maintain their shape and volume regardless of the container they are placed in. Therefore, if the shape of something changes when it is placed in different containers, it cannot be a solid.
7.
When something has volume, it takes up __________.
Correct Answer
space
Explanation
When something has volume, it means that it occupies a certain amount of physical space. Volume refers to the amount of three-dimensional space that an object or substance occupies. Therefore, the correct answer is "space" because something with volume takes up space.
8.
When matter in this state is placed in a container, it takes up all the space in that container. What is this state?
Correct Answer
Gas
Explanation
Gas is the state of matter that takes up all the space in a container. Unlike solids and liquids, gases have particles that are not fixed in position and are able to move freely. This allows them to expand and fill the entire volume of the container they are placed in. The particles in a gas are widely spaced and have high kinetic energy, resulting in the ability to occupy any available space. Therefore, the correct answer is gas.
9.
What state of matter are the particles the farthest apart?
Correct Answer
D. Plasma
Explanation
Plasma is the state of matter in which particles are the farthest apart. In plasma, atoms or molecules are ionized, meaning they have lost or gained electrons, resulting in a highly charged state. This leads to the particles being widely spaced and not bound together, allowing them to move freely and independently.
10.
What state of matter are the particles the closest together?
Correct Answer
A. Solid
Explanation
In a solid state, particles are tightly packed and have the least amount of space between them compared to other states of matter. The particles in a solid are held together by strong intermolecular forces, causing them to vibrate in a fixed position. This close arrangement of particles gives solids their rigid shape and high density. In contrast, particles in liquids and gases have more space between them, allowing them to move more freely. Plasma, on the other hand, consists of highly energized particles that have been stripped of their electrons, resulting in a state where particles are not closely packed together.
11.
What state of matter are the particles in this picture?
Correct Answer
C. Gas
Explanation
The particles in the picture are in a gaseous state because they are spread out and not tightly packed together. In a gas, the particles have high energy and move freely, filling the space available to them.
12.
What state of matter is rain?
Correct Answer
B. Liquid
Explanation
Rain is in the liquid state of matter. When water vapor in the atmosphere condenses and forms droplets, it falls to the ground as rain. Liquids have a definite volume but no definite shape, and they can flow and take the shape of their container. Rain exhibits these characteristics, making it a liquid.
13.
What state of matter has no shape or volume?
Correct Answer
C. Gas
Explanation
Gas is the state of matter that has no shape or volume. Unlike solids and liquids, gases do not have a fixed shape and can expand to fill the entire space available to them. They also do not have a fixed volume and can be compressed or expanded easily. Gas particles are in constant random motion and have a lot of space between them, which allows them to move freely and take the shape and volume of their container.
14.
What state of matter are the particles in this picture of?
Correct Answer
A. Solid
Explanation
The particles in the picture are closely packed together and have a fixed shape and volume, indicating that they are in a solid state of matter.
15.
Which states of matter can be compressed?
Correct Answer
C. Gas
Explanation
Solid is a state of matter that has a definite shape, volume and cannot be compressed. Liquid has a no definite shape, has definite volume and cannot be compressed. Gas has no definite shape, volume and can be compressed.
16.
If the shape of something changes when it is placed in different containers, it cannot be a _____________.
Correct Answer
solid
Explanation
If the shape of something changes when it is placed in different containers, it cannot be a solid. Solids have a fixed shape and volume, meaning they do not change their shape or take the shape of their container. Liquids and gases, on the other hand, are able to change their shape to fit the container they are placed in, making them the likely options in this scenario.
17.
When something has volume, it takes up __________.
Correct Answer
space
Explanation
When something has volume, it means that it occupies a certain amount of physical space. Volume refers to the amount of three-dimensional space that an object or substance occupies. Therefore, the correct answer is "space".
18.
Matter that cannot be compressed _______________________________.
Correct Answer
B. Is a solid
Explanation
Only gas can be compressed.
19.
1. How many basic states of matter exist?
Correct Answer
C. 3
Explanation
The correct answer is 3 because there are three basic states of matter: solid, liquid, and gas. These states are determined by the arrangement and movement of particles. In a solid, particles are tightly packed and vibrate in place. In a liquid, particles are close together but can move past each other. In a gas, particles are spread out and move freely. Other states, such as plasma and Bose-Einstein condensate, are considered to be more specialized or extreme forms of matter.
20.
What states of matter water be?
Correct Answer
D. All of the above
Explanation
Water can exist in all three states of matter: solid, liquid, and gas. In its solid state, water forms ice, while in its liquid state, it is a common liquid that we use in our daily lives. When water reaches its boiling point, it turns into a gas called water vapor. Therefore, water can be found in all of these states depending on the temperature and pressure conditions.
