Some of the thermodynamic parameters are state variables while some are process variables. Some grouping of the parameters are given. Choose the correct one.

Options

A. State variables: Temperature, NO. of moles
Process variables, internal energy work done by the gas.
B. Stte variables: Volume. Temperature
Process variables: Internal enrgy, work done by the gas.
C. State variables: work done by the gas, heat rejecected by the gas
Process variables: Temperature, volume
D. State variables: Internal energy, volume
Process variables: Work done by the gas, heat absorbed by the gas.

Explanation

To solve the question regarding the classification of thermodynamic parameters into state variables and process variables, we need to understand the definitions and characteristics of each type of variable.

### Step-by-Step Solution:

1. **Define State Variables**:
- State variables are properties that depend only on the current state of the system and not on how the system reached that state. Examples include temperature, pressure, volume, and internal energy.

2. **Define Process Variables**:
...
