The following equations represent the four parts (a, b, c, and d) of a cyclic process with a gas. the gas does not obey the ideal gas law. w is the work done by the system on the environment and consequently q−w=δuint. w=(3.0×105n/m2)(0.020m3−0.010m3)+0+ (1.0×105n/m2)(0.010m3−0.020m3)+0 δuint=(3/2)(1.0mole)(8.3j/mole⋅k)[( 700k−360k)+(480k−700k)+(240k−480k)+ (360k−240k)] q=qa+qb+qc+qd
