One cubic meter of an ideal gas at 600 k and 1 000 kpa expands to four times its initial volume sketch each path on a single pv diagram by a mechanically reversible, constant p-process by a mechanically reversible, adiabatic process (2) (7) (13) 41 42 4 3 for each case, calculate the final temperature, pressure, and the work done by the gas take cp 21 j/mol k
