Answer:
A body is said to be in thermal equilibrium where all the system temperatures are the same.
A body is said to be in thermodynamic equilibrium if all three requirements of equilibrium are met
Step-by-step explanation:
A body is said to be in thermal equilibrium where all the system temperatures are the same. In this case, there will be no temperature gradient between the system and the environment.
while, A body is said to be in thermodynamic equilibrium if all three requirements of equilibrium are met, i.e. mechanical equilibrium, chemical equilibrium and thermal equilibrium.
