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: -Heat flows from hot to cold objects. When a hot and a cold body are in thermal contact, they exchange heat energy until they reach thermal equilibrium, with the hot body cooling down and the cold body warming up.

Detailed explanation-3: -The transfer of heat goes from the hot object to the cold object. We can imagine a system, however, in which the heat is instead transferred from the cold object to the hot object, and such a system does not violate the first law of thermodynamics.

Detailed explanation-4: -From the second law of thermodynamics, we know that the entropy of a closed system can never decrease. So, from this law we get that heat will always flow from a state of higher temperature to a state of lower temperature.

Detailed explanation-5: -Under normal conditions and in nature, heat energy will ALWAYS flow from the warmer object to the cooler object. Heat energy will flow from one substance to another until the two substances have the same temperature. This is known as Thermal Equillibrium.
