A gas has an initial volume of $2.00 \mathrm{~m}^{3}$. It is expanded to three times its original volume through a process for which $P=\alpha V^{3},$ with $\alpha=4.00 \mathrm{~N} / \mathrm{m}^{11} .$ How much work is done by the expanding gas?

Key Concepts

Process Path Dependence

The work done by a system in a thermodynamic process depends on the specific relationship between pressure and volume, commonly known as the process path. Since work is a path-dependent quantity, knowing the functional form of pressure as a function of volume is essential to determine the exact work performed during the transformation.

Integration of Pressure-Volume Functions

To calculate the work done when the pressure varies with volume, one must perform a definite integral of the pressure function over the volume change. This involves using integration techniques, such as the power rule, to evaluate the area under the pressure-volume curve between the initial and final states.

Thermodynamic Work

In thermodynamics, work is defined as the energy transferred by a system when a force is applied over a distance. In the context of gases, it refers to the energy associated with the expansion or compression of the gas. The work done by the gas is typically calculated using the integral of pressure with respect to volume over the path of the process.
