(a) δ … WebA cyclic process could be reversible or irreversible. Cyclic process are those processes, during which the system undergoes a succession of processes, and eventually ends up at the same state that it started from, thus executing a cycle. The system doesn’t not retrace its path back to the start. [Image Courtesy - Google images] dyson hot and cool alternative
