Which of the following is equivalent to a temperature of -50˚C?
Correct answer: B. 223K
- A. -223K
- B. 223K
- C. -323K
- D. 323K
Explanation
Conversion of Temperature from Celsius to Kelvin:TK = TC + 273TK = -50oC + 273TK = 223 KHence, B is the correct option.

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.
