**Question 8-1:**

A van der Waals gas and an ideal gas are originally at the same pressure, temperature, and volume. If each gas undergoes a reversible isothermal compression, which gas will experience the greater change in entropy?

**Explanation:**

This question involves comparing the change in entropy between a van der Waals gas and an ideal gas under the same initial conditions (pressure, temperature, and volume) after undergoing a reversible isothermal compression. The ideal gas follows the ideal gas law without interactions considered among molecules, while the van der Waals gas equation accounts for the size of molecules and intermolecular forces. Understanding these differences can help determine which gas will experience a greater change in entropy.
