Question

Three bodies A, B, C are at thermal equilibrium temperature of A is30 degree Celsius temperature of B and C is

Answer 1

Answer:

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 A is 30°C then the B and C will have same 30°C temperature.

Hence, the answer is 30°C.
