Thermodynamics

Two bodies are said to be in thermal equilibrium when…

• No transfer of heat takes place when they are are placed in contact.

• Heat get transferred from body at higher temperature to body at lower temperature.

• Heat get transferred from body at lower temperature to body at higher temperature.

• None of the above

If two bodies A and B are in thermal equilibrium and A and C are also in thermal equilibrium then B and C are also in thermal equilibrium.

This is…
