Question

Three bodies A, B and C are in thermal equilibrium. The temperature of B is 45°C. then the temperature of C is
a) 45°C
b) 50°C
c) 40°C
d) any temperature

Answer 1

Hey.

Here is the answer.

As the bodies are in thermal equilibrium , so their temperature will be same.

So, temperature of C will be 45℃

Thanks.

Answer 2

Answer:

45°C temperature.

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.

so the answer is 45°C temperature.
