a) There are two adiabatic processes. b) There are two constant-pressure processes. c) Work occurs for all four processes. d) Each process is a reversible process.

Explanation / Answer

Carnot cycle consists of four processes - two reversible isothermal process and two reversible adiabatic process. The Pressure -volume (P-V) graph of Carnot cycle is not exact straight lines rather than it have a slope for pressure /colume along X and Y axis. Hence, constant pressure is not possilble in Carnot cycle process.
