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.)
2. What is the final temperature, in deg R?
3. What is the final volume occupied by the Gas, in in^3?
