A gas originally at `1.10atm` and `298K` underwent a reversible adiabatic expansion to `1.00atm` and `287K`. What is the molar heat capacity of the gas?

Explanation

To solve the problem of finding the molar heat capacity of the gas undergoing a reversible adiabatic expansion, we can follow these steps:

### Step 1: Understand the relationship in adiabatic processes
For a reversible adiabatic process, we can use the relationship between temperature and pressure:
\[ \frac{T_2}{T_1} = \left(\frac{P_2}{P_1}\right)^{\frac{C_P}{R}} \]
