Question

___is the energy of random motion of constituent molecules constituting the body. It flows from a hot body to a cold body.

Answer 1

Heat is the energy of random motion of constituent molecules constituting the body. It flows from a hot body to a cold body. If we touch warm water, we feel hot because heat energy from warm water passes to our hand. Similarly, if we touch a cube of ice, we feel cool because heat energy from our hand passes to the cube of ice.
