Question

When vander waal's gas undergoes free expansion, then its temperature decreases.iitjee?

Answer 1

A van der Waals gas undergoes an isothermal reversible expansion under conditions such that z > 1. Is the work done more or less than if the gasfollowed the ideal gas law? We have for a van der Waals gas is which implies that the gas exerts greater pressure. For van der Waals gashaving corresponding pressure
