SSC MTS EXAM

Detailed explanation-1: -When two objects have different temperatures, heat is transferred. The cooler object gets warmer until the two objects have the same temperature. Heat energy always flows from the warmer object to the cooler object.

Detailed explanation-2: -The Second Law of Thermodynamics can be rephrased in several ways. Fundamentally, it says that heat always flows from hot objects to cold objects (unless work is exerted to make it flow the other direction).

Detailed explanation-3: -In physics, the second law of thermodynamics says that heat flows naturally from an object at a higher temperature to an object at a lower temperature, and heat doesn’t flow in the opposite direction of its own accord.
