Methane (considered to be an idela gas) initially at `25^(@)C` and 1 bar pressure is heated at constant pressure until the volume has doubled. The variation of the molar heat capacity with absolute temperature is given by
`C_(P)=22.34+48.1xx10^(-3)T`
where `C_(P)" in "JK^(-1)mol^(-1)`. Calculate molar (a) `DeltaH` (b) `DeltaU`.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Determine the Initial and Final Conditions
- **Initial Temperature (T1)**: 25°C = 298 K
- **Initial Pressure (P)**: 1 bar
- **Final Volume (V2)**: 2 * V1 (since the volume has doubled)

### Step 2: Calculate the Final Temperature (T2)
