What are the conditions for thermodynamic equilibrium?

Explanation

To determine the conditions for thermodynamic equilibrium, we need to identify and explain the three key conditions that must be satisfied:

### Step 1: Identify Thermal Equilibrium
The first condition for thermodynamic equilibrium is **thermal equilibrium**. This means that there should be no temperature difference within the system. If all parts of the system are at the same temperature, then thermal energy is evenly distributed, and there is no heat flow between different parts of the system.

### Step 2: Identify Mechanical Equilibrium
The second condition is **mechanical equilibrium**. For a system to be in mechanical equilibrium, there should be no unbalanced forces acting on it. This means that the net force and net torque acting on the system must be zero. If there are no unbalanced forces, the system will not experience any acceleration or movement, ensuring stability.
