Think of at least five examples EACH of a REVERSIBLE and IRREVERSIBLE process that is evident in everyday life. Provide a short Explanation of each examples.

Water stored in a large, well-insulated storage tank at 21oC, and atmospheric pressure is being pumped at steady state from this tank by a pump at the rate of 40m3/h. The motor driving the pump supplies energy at the rate of 8.5 k.W. The water is used as a cooling medium and passes through a heat exchanger where 255 k.W of heat is added to the water. The heated water then flows to a second large, vented tank, which is 25 m above the first tank. Determine the final temperature of the water delivered to the second tank.

For irreversible adiabatic expansion or compression of an ideal gas, work is equal to the internal energy change. Select one: True False

Is energy added to the gas by heating or removed by cooling in each cycle? Support your claim in a coherent paragraph-length response that qualitatively compares the amounts of energy added to the gas by heating or removed by cooling in the two cycles and refers to the work done on the gas and the change in internal energy of the gas.

A system undergoes a cycle while receiving 1400 kJ by heat transfer at a temperature of 700 K and discharging 700 kJ by heat transfer at (a) 250 K, (b) 350 K, (c) 450 K.  Determine the nature of the cycle in each of these cases?
