Change in temperature of a body is 50°C. The change in temperature on the Kelvin scale is:
Correct answer: A. 323 K
- A. 323 K
- B. 50 K
- C. 223 K
- D. 70 K
Explanation
The Kelvin temperature is obtained by adding 273.15 to the Celsius temperature. Therefore, 50°C + 273.15 = 323.15 K.

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.
