Question

Which of these would best describe the outcome of increasing the kinetic energy of the molecules in the above picture? A) The temperature will increase. B) The temperature will decrease. C) The temperature will remain unchanged. D) The temperature would fluctuate up and down.

Answer 1

Answer: Option (A) 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.

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

Thus, we can conclude that temperature will increase best describes the outcome of increasing the kinetic energy of the molecules in the above picture.
