Final answer:
When the temperature of a substance decreases, the average kinetic energy of its particles also decreases. This is because the temperature of a substance is proportional to the average kinetic energy of its particles. The slower the particles move, the lower the kinetic energy.
Explanation:
The question refers to the relationship between the temperature of a substance and the average kinetic energy of its particles. According to the kinetic-molecular theory, the temperature of a substance is proportional to the average kinetic energy of its particles. When the temperature of a substance rises, the particles vibrate more in solids or move more rapidly in liquids and gases, indicating an increase in kinetic energy. Conversely, if the temperature decreases, the kinetic energy also decreases, and the particles move more slowly.
For instance, when the temperature of a gas increases, its average kinetic energy increases, more molecules have higher speeds and fewer molecules have lower speeds. The distribution shifts towards higher speeds overall. If the temperature decreases, the opposite happens: the average kinetic energy decreases, more molecules have lower speeds and fewer molecules have higher speeds. The distribution shifts towards lower speeds overall.

Mixtures are materials composed of two or more kinds of substances that still possess their original properties. Mixtures can also be said to represent a combination of several substances, elements or compounds
There are two types of mixtures, i.e., homogeneous mixture (or solution) and heterogeneous mixture.
- Homogeneous mixture: mixture which each part contains a similar amount of solute, for example, vinegar acid solution, sugar solution, and salt solution.
- Heterogeneous mixes: mixtures of which each part contains an unequal amount of solute, for example, river water, sewage water, and coffee drinks.
The solution is a homogeneous mixture of two or more substances that dissolve one another and each of the constituent substances cannot be distinguished physically anymore.
- The solution consists of two components, i.e., solute and solvent.
- For example, a salt solution consists of salt as a solute and water as a solvent.
In chemistry, we already know the phase of matter or state of matter, i.e., solid (s), liquid (l), gas (g), and aqueous (aq). Every chemical solution in a reaction is labeled as an aqueous phase, e.g, as a salt solution.
Consider the following examples:
as a solid metal iron, an element.
as liquid water.
as ice solids.
as water vapor with a gaseous phase.
are compounds of the same chemical formula but different phases.

Answer : The correct option is, Mass
Explanation :
As we know that there are 3 states of matter :
Solid state : It is a state in which the particles are closely packed and does not have any space between them. This state have a definite shape and volume.
Liquid state : It is a state in which the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. This state have a definite volume but does not have a fixed shape.
Gaseous state : It is a state in which the particles are loosely arranged and have a lot of space between them. This state have indefinite volume as well as shape.
If we are taking 100 grams of ice then after melting its mass remains same but its shape, volume and temperature will be changed and after evaporation its mass remains same but its shape, volume and temperature will be changed.
Hence, the mass will stay constant, no matter if the substance is in the solid, liquid, or gas state.
Answer:
The correct answer is mass
Explanation:
Hello!
Let's solve this!
In the solid state, where the molecules occupy a definite place, and remain still, the shape and volume remain constant.
In the liquid state the molecules take the form of the container that contains them. So the shape is not defined but the volume is defined.
In the gaseous state the molecules are disordered, and have neither defined volume nor shape.
In all three states the mass remains constant.
The temperature causes the change of state.
We conclude that the correct answer is mass
