Unformatted text preview: the Increase of Entropy Principle 7–1C Does the temperature in the Clausius inequality relation have to be absolute temperature? Why? 7–2C Does a cycle for which inequality? Why? dQ 0 violate the Clausius 7–3C Is a quantity whose cyclic integral is zero necessarily a property? 7–4C Does the cyclic integral of heat have to be zero (i.e., does a system have to reject as much heat as it receives to complete a cycle)? Explain. 7–5C Does the cyclic integral of work have to be zero (i.e., does a system have to produce as much work as it consumes to complete a cycle)? Explain. 7–6C A system undergoes a process between two fixed states first in a reversible manner and then in an irreversible manner. For which case is the entropy change greater? Why? 2 7–7C Is the value of the integral 1 dQ/T the same for all processes between states 1 and 2? Explain. 2 7–8C Is the value of the integral 1 dQ/T the same for all reversible processes between states 1 and 2? Why? 7–9C To determine the entropy change for an irreversible 2 process between states 1...
