Question

Three bodies A, B and C are in thermal equilibrium and the temperature

of A is 30౦C and the temperature of B is 303K, and the temperature of C

is 420K. In the three bodies A, B and C from which body to which body
heat flows?​

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 B is 45°C then the C will have same 45°C temperature.

Hence, the answer is 45°C.
