Two systems are said to be in thermal equilibrium if and only if:

there can be a heat flow between them even if they are at different temperatures

there cannot be a heat flow between them even if they are at different temperatures

there is no heat flow between them

their temperatures are slightly different

Two systems are said to be in thermal equilibrium if is no heat transfer takes place as both the systems have same temperature.
