1. If an accumulator using a 'dead weight ballast' against an initial gas volume of 1500 in^3 is heated from 80degF to 200degF, what kind of process is it? (Dead weight ballast means there is a weight stacked on top of the gas piston. This weight moves up or down by the action of the gas that is trapped by the piston.)
