Question

Which defines the average kinetic energy of a system’s particles? density pressure temperature volume

Answer 1

Answer: Option (c) is the correct answer.

Explanation:

Relation between kinetic energy and temperature is as follows.

                $K.E \propto \frac{3}{2}kT$

As, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then there will also occur increase in kinetic energy of the particles of a substance.

Therefore, when gas particles move more slowly then it means kinetic energy of gas particles is very low. It also implies that temperature is low.

Similarly, when kinetic energy is high then there it means temperature is also high.

Thus, we can conclude that temperature defines the average kinetic energy of a system’s particles.

Answer 2

Answer:

Temperature

Explanation:

The kinetic energy is proportional to the temperature. That is, temperature is a measure of the kinetic energy of atoms and molecules that are part of a system.

This can be explained by kinetic theory.
