Heat is associated with

Options

A. Kinetic energy of random motion of molecules
B. Kinetic energy of orderly motion of molecules
C. Total kinetic energy of random and orderly motion of molecules
D. Kinetic energy of random motion in some cases and kinetic energy of orderly motion in other

Answer

A

Explanation

We know that as temperature increases vibration of molecules about their mean position increases hence, kinetic energy associated with random motion of molecules increases.
