Question

Q1. The direction of heat flow between two body depends on which of the following?

Their area of contact

Their specific heat

Their temperatures

Their latent heat

Accepted Answer

Answer : Their temperatures

The direction of heat transfer is from a region of high temperature to another region of lower temperature, and is governed by the Second Law of Thermodynamics. Heat transfer changes the internal energy of the systems from which and to which the energy is transferred. The objects will exchange thermal energy, until thermal equilibrium is reached, i. e. until their temperatures are equal.
