A system contains a fluid at a temperature of 70 °C and 1 bar. It undergoes a reversible process during which the temperature of the system remains constant. Given that the heat transfer to the fluid during the process is 100 kJ, evaluate

a. the increase in entropy.

b. if the system has a mass of 2.31 kg. Evaluate the increase in specific entropy of the system.

c. If a second fluid system, identical to the first one undergoes an irreversible isothermal process from the same initial state to the same final state as above; and the heat transfer to the fluid in this irreversible process is 180 kJ; evaluate the increase in entropy of the fluid.
