Question

Heat is associated with
(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 1

Answer:

a) kinetic energy of random motion of molecules

Answer 2

Answer:

1 Answer. (a) When a body is heated its temperature rises and in liquids and gases vibration of molecules about their mean position increases, hence kinetic energy associated with random motion of molecules increases. So, thermal energy or heat associated with the random and translatory motions of molecules
