Temperature of `1mol` of a gas is increased by `1^(@)` at constant pressure. The work done is

Options

A. `R`
B. `2R`
C. `R//2`
D. `3R`

Explanation

To solve the problem of finding the work done when the temperature of 1 mole of a gas is increased by 1°C at constant pressure, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Work Done Formula**:
The work done (W) on or by a gas at constant pressure is given by the formula:
\[
W = P \Delta V
