To solve the problem, we need to calculate the change in internal energy (ΔU) and the change in enthalpy (ΔH) for the given process. Here's a step-by-step breakdown of the solution:
### Step 1: Identify the given data
- Heat added (Q) = 1.0 kcal
- Initial volume (V1) = 1.2 L
- Final volume (V2) = 1.5 L
- Constant pressure (P) = 1 atm
- Conversion factor: 1 L·atm = 100 J
