Which of the following is equivalent to a temperature of 150K?
Correct answer: B. -123⁰C
- A. 123⁰C
- B. -123⁰C
- C. 423⁰C
- D. -423⁰C
Explanation
Temperature in degrees Celsius + 273= Temperature in Kelvinx+273=150x= -273+150x= -123 C which is option B.

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.
