A certain amount of a monatomic ideal gas undergoes the process shown in Figure, in which its pressure doubles and its volume triples. Tn terms of the number of moles, n,the initial pressure, Pi,and the initial volume, Vi, determine (a) the work done by the gas W,(b) the change in internal energy of the gas U,and (c) the heat added to the gas Q.
