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
Correct option is A) Heating up a substance excites the molecules of that substance making the molecules moves vigorously thus giving velocity to the molecules and we know kinetic energy of a body is by the virtue of its motion.
