Detailed explanation-1: -Heat Transfer: The movement of heat from a warmer object to a colder one – when two substances at different temperatures are mixed together, heat flows from the warmer body to the cooler body until they reach the same temperature (Zeroth Law of Thermodynamics – Thermal Equilibrium).

Detailed explanation-2: -Throughout the universe, it’s natural for energy to flow from one place to another. And unless people interfere, thermal energy-or heat-naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation.
