Question

There is an increase in temperature of an object then the kinetic energy of the object __________

(a) decreases

(b) increases

(c) remains the same

(d) it is not related to the temperature

This question was addressed to me in quiz.

I want to ask this question from States of Matter topic in section States of Matter of Chemistry – Class 11

Answer 1

The correct answer is (b) increases

To elaborate: From the kinetic molecular theory of gases we can know that the kinetic energy of an object is proportional directly to the Absolute Temperature of that object so when the temperature of an object increases obviously the kinetic energy also increases.
