Question

Describe the analytical methid for determining the work done during the expansion of gas

Answer 1

Explanation:

Calculate the work done of n moles of a vander Waals gas in an isothermal expansion from Vi to Vf. Here p is the pressure, V is the volume, R is the gas constant, T is the temperature, n is the number of moles, a and b are the van der Walls gas constant. First we have to find out the pressure p of the gas.

Answer 2

Answer:

Work is a path function. So work done on the gas depends upon the path. The area under pv diagram gives the work done on the gas between initial state i and final state f. Here p is the pressure and dV is the change in volume.
