Consider a piston-cylinder device. Within this device, a quasi-equilibrium process occurs for which the pressure changes according to the equation p = 300V2 + 1000 V + 1000, with p, pressure, in psfa, and V, volume, in cubic feet. The volume changes from 8.0 to 4.0 ft3. Calculate the work in BTUs. Sketch this process on a p-V diagram. Highlight the area of the graph that represents work.
