One moles of an ideal gas which `C_(V) = 3//2 R` is heated at a constant pressure of `1 atm` from `25^(@)C` to `100^(@)C`. Calculate `DeltaU, DeltaH` and the entropy change during the process.

Explanation

To solve the problem, we need to calculate the change in internal energy (ΔU), the change in enthalpy (ΔH), and the entropy change (ΔS) for one mole of an ideal gas heated at constant pressure from 25°C to 100°C.

### Step 1: Calculate ΔU

The change in internal energy (ΔU) for an ideal gas can be calculated using the formula:

\[
\Delta U = n C_V \Delta T
