Calculate the work of an isobaric reversible expansion of three moles of an ideal gas while it is heated from 298 K to 400 K.

Explanation

To calculate the work done during an isobaric reversible expansion of three moles of an ideal gas heated from 298 K to 400 K, we can follow these steps:

### Step 1: Understand the Isobaric Process
In an isobaric process, the pressure remains constant. The work done (W) during an isobaric process can be calculated using the formula:

\[ W = -nR(T_2 - T_1) \]
