`C_(P) -C_(V)` for an ideal gas is………….. .

Explanation

To solve the question `C_(P) - C_(V)` for an ideal gas, we will follow these steps:

### Step 1: Understand the definitions of Cp and Cv
- **Cp** (specific heat at constant pressure) is the amount of heat required to raise the temperature of a unit mass of gas by one degree Celsius at constant pressure.
- **Cv** (specific heat at constant volume) is the amount of heat required to raise the temperature of a unit mass of gas by one degree Celsius at constant volume.

### Step 2: Write the equations for heat transfer
- At constant pressure, the heat added is given by:
...
