At `27^(@)C`, one mole of an ideal gas is compressed isothermally and reversibly from a pressure of `20atm` to `100 atm`. Calculate `DeltaE` and `q.(R = 2 calK^(-1)mol^(-1))`

Explanation

To solve the problem, we need to calculate the change in internal energy (ΔE) and the heat exchanged (q) for the isothermal compression of one mole of an ideal gas from a pressure of 20 atm to 100 atm at a temperature of 27°C.

### Step-by-Step Solution:

1. **Convert Temperature to Kelvin:**
\[ T = 27°C + 273 = 300 K \]
