Question

A steel container, equipped with a piston, contains 21 mol of an ideal gas at 465 K. The container is compressed isothermally to 90% of its original volume. How much work is done on the gas? The ideal gas constant is R = 8.314 J/mol x K.

Answer 1

There's an equation that defines the work done compressing a gas:\[W=-\int\limits_{V _{i}}^{V _{f}}\frac{ nRT }{ V }dV=-nRT \ln \left(\frac{ V _{f} }{ V _{i} } \right)\]
