Hey I'm Chloe, Can you Help me Thank you :) Q: how can you tell if two objects are in thermal equilibrium?

Two objects are in thermal equilibrium if they are in close contact that allows either to gain energy from the other, but nevertheless, no net energy is transferred between them. Even when not in contact, they are in thermal equilibrium if, when they are placed in contact, no net energy is transferred between them.
