Which of the following phenomenon is the fastest for the transmission of heat
Correct answer: C. radiaton
- A. convection
- B. conduction
- C. radiaton
- D. all of these
Explanation
Radiation is the fastest mode of heat transfer because it doesn't rely on a medium for propagation. In radiation, heat is transferred through electromagnetic waves and can occur even in a vacuum.

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.
