What are diathermic and adiabatic containers?

Explanation

To understand the concepts of diathermic and adiabatic containers, we need to look at the definitions of diathermic and adiabatic walls or boundaries.

### Step-by-Step Solution:

1. **Definition of Diathermic Containers**:
- Diathermic containers are those that have walls or boundaries that allow the transfer of heat (energy) between the system inside the container and the surroundings.
- This means that if there is a temperature difference between the system and the surroundings, heat will flow through the walls of the container until thermal equilibrium is reached.
