Question

Three objects,A at 30degree celsius ,B at 303 kelvins and C at 420kelvins are in thermal contact
which are in thermal equilibrium among A,B and C
FROM WHICH OBJECT TO ANOTHER HEAT TRANSFORMRD

Answer 1

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.
