Anything that has mass and takes up space is
Correct Answer
C. Matter
Explanation
The given statement defines matter as anything that has mass and takes up space. This means that matter includes all physical substances and objects, such as solids, liquids, and gases. Both volume and density are properties of matter, but they do not encompass the entire definition of matter itself. Therefore, the correct answer is matter.
2.
The amount of material that an object has in it is its
Correct Answer
B. Mass
Explanation
Mass is the correct answer because it refers to the amount of material that an object contains. It is a measure of the quantity of matter in an object, regardless of its size or shape. Volume, on the other hand, refers to the amount of space occupied by an object, while a meter is a unit of measurement for length. Therefore, mass is the most appropriate choice in this context.
3.
A ________________ is a kind of mixture in which a substance spreads evenly throughout another substance.
Correct Answer
B. Solution
Explanation
A solution is a type of mixture where one substance is evenly distributed throughout another substance. In a solution, the particles of the solute (the substance being dissolved) are dispersed and mixed uniformly with the particles of the solvent (the substance doing the dissolving). This results in a homogeneous mixture where the solute particles are not visible and cannot be easily separated from the solvent. Solutions can be formed with various combinations of substances, such as solid solutes dissolved in liquid solvents or gases dissolved in liquid solvents.
4.
The unit for measuring the volume of a large box is a _________
Correct Answer
B. Cubic meter
Explanation
The correct answer is cubic meter. Cubic meter is the unit used to measure the volume of a large box. It represents the amount of space occupied by the box in three dimensions - length, width, and height. The term "cubic" indicates that the unit is being used to measure volume, while "meter" is the base unit of length in the metric system. Therefore, cubic meter is the appropriate unit for measuring the volume of a large box.
5.
The unit used to measure the volume of a liquid is a _________________
Correct Answer
A. Liter
Explanation
The unit used to measure the volume of a liquid is a liter. A liter is a metric unit of volume that is commonly used to measure liquids. It is equal to 1000 milliliters or 1 cubic decimeter. The liter is a convenient unit for measuring liquid volumes because it is easily divisible into smaller units such as milliliters and centiliters.
6.
The amount of mass in a certain volume of matter is called
Correct Answer
B. Density
Explanation
Density is the correct answer because it refers to the amount of mass present in a given volume of matter. It is a measure of how tightly packed the particles are in a substance. Density is calculated by dividing the mass of an object by its volume.
7.
A _____________ does not produce a different kind of matter.
Correct Answer
C. pHysical change
Explanation
A physical change refers to a change in the physical properties of a substance, such as its shape, size, or state, without altering its chemical composition. In other words, during a physical change, the matter remains the same, and no new substances are formed. Both the boiling point and melting point are specific temperatures at which substances change their states, but these changes are still considered physical changes because they do not result in the formation of different kinds of matter.
8.
Water changes from ice to liquid water at its_______________
Correct Answer
A. Melting point
Explanation
Water changes from ice to liquid water at its melting point. This is the temperature at which the solid ice transitions into liquid water. During this phase change, the ice absorbs heat energy from its surroundings and breaks the intermolecular bonds holding its molecules together. This results in the formation of liquid water molecules that are free to move and flow. The melting point of water is 0 degrees Celsius or 32 degrees Fahrenheit.
9.
The temperature at which q liquid changes to a gas is its_________
Correct Answer
A. Boiling point
Explanation
The temperature at which a liquid changes to a gas is referred to as its boiling point. This is the point at which the vapor pressure of the liquid equals the atmospheric pressure, causing the liquid to rapidly convert into a gas. It is a characteristic property of each substance and can vary depending on factors such as pressure.
10.
The ________________ of water,or the temperature at which its changes from liquid to a solid,is 0 c
Correct Answer
A. Freezing point
Explanation
The freezing point of water is the temperature at which it changes from a liquid to a solid, and this temperature is 0°C.
11.
A change in matter, as in baking a cake, is a example of a __________
Correct Answer
A. Chemical change
Explanation
Baking a cake involves a chemical change because the ingredients undergo a chemical reaction to form a new substance with different properties. The heat from the oven causes the ingredients to react, resulting in a cake that is different from the original batter. This change is not reversible, as it cannot be undone to recreate the original ingredients. Therefore, baking a cake is an example of a chemical change.
