Which of the following condition must be true for transfer of energy from an object at temperature T1 to another object at temperature T2 ?
Correct answer: C. T1>T2
- A. T1 =T2
- B. T1<T2
- C. T1>T2
- D. None of these
Explanation
Heat transfer occurs from the hotter object to the colder object, as described by the second law of thermodynamics.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
