Heat is supplied at constant pressure to diatomic gas. The part of this heat which goes to increase its internal energy will be

Options

A. `5/7`
B. 3
C. `2/5`
D. `2/3`

Explanation

To solve the problem of how much of the heat supplied at constant pressure to a diatomic gas goes into increasing its internal energy, we can follow these steps:

### Step 1: Understand the Heat Supplied at Constant Pressure
The heat supplied to a gas at constant pressure (Q) can be expressed using the formula:
\[ Q = m C_p \Delta T \]
where:
- \( m \) is the mass of the gas,
- \( C_p \) is the specific heat at constant pressure,
...
