1. Close system example An inventor claims to have a "black box" which transforms 1 mol of air from 500K at 2 bar to 350K at 1 bar, generates 2000J of work and transfer an undetermined amount of heat to a heat reservoir at 300 K Determine if this process may be potentially possible assuming that air is an ideal gas with Cp 7/2R. Start by assessing AStotal - ASystem + ASurrounding
