Question

3.
Three bodies A, B and C are in thermal equilibrium. The temperature of B is 45°C. Then the temperature
of C is .
​

Answer 1

Answer:

45°c

Explanation:

According to zeroth law of thermodynamics if two thermodynamic system are in thermal equilibrium with a third them they are in thermal equilibrium with each other.

Accordingly thermal equilibrium between system is a transitive relation. So, If A,B and C are in thermal equilibrium & temperature of B is 45°C then the C will have same 45°C temperature.

Hence, the answer is 45°C.
