Although heat is a path function but heat absorbed by the system under certain specific conditions is independent of path. What are those conditions ? Explain.

Explanation

To address the question of when heat absorbed by a system becomes independent of the path taken, we can identify two specific conditions: constant volume and constant pressure. Let's break down the explanation step by step.

### Step-by-Step Solution:

1. **Understanding Path Functions**:
- Heat (Q) and work (W) are classified as path functions in thermodynamics. This means that the values of heat and work depend on the specific path taken during a process, rather than just the initial and final states of the system.

2. **Condition 1: Constant Volume**:
