### Thermodynamics Problem

**Problem Statement:**

A pure gas is compressed isothermally at 300K from 10 atm to 20 atm in an irreversible process. During this process, the system releases 3kJ of heat (q) to the surroundings.

#### Questions:

1. What is ΔS (entropy change) of the gas?
2. If the gas is compressed isothermally at 300K from 10 atm to 20 atm in a reversible process, what is ΔS (entropy change)?

**Diagrams/Graphs:**

There are no diagrams or graphs present in the original text.
