Choose the correct answer. A thermodynamic state function is a quantity
(i) used to determine the heat changes
(ii) whose value is independent of path
(iii) used to determine pressure - volume work
(iv)whose the value depends on temperature only.

Explanation

To answer the question regarding thermodynamic state functions, let's analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Thermodynamic State Functions**:
- A thermodynamic state function is a property of a system that depends only on its current state, not on how it arrived at that state. Examples include internal energy, enthalpy, entropy, and pressure.
