Question 1
The entropy of universe tends to
Question 2
A system of 100 kg mass undergoes a process in which its specific entropy increases from 0.3 kJ/kg K to 0.4 kJ/kg K. At the same time, the entropy of the surroundings decreases from 80 kJ/K to 75 kJ/K. The process is:
Question 3
One kg of an ideal gas (gas constant R=287 J/kg.K) undergoes an irreversible process from state-1 (1 bar, 300 K) to state -2 (2 bar, 300 K). The change in specific entropy (s2-s1) of the gas (in J/kg.K) in the process is ______
Question 4
For a reversible power cycle, the operating temperature limits are 800K and 300K. 400kJ of heat is supplied to this cycle from high temperature source.The unavailable work will be.
Question 5
1000 kJ/s of heat is transferred from a constant temperature heat reservoir maintained at 1000 K to a system at a constant temperature of 500 K. The temperature of the surroundings is 300 K. The net loss of available energy as a result of this heat transfer is:
