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?

7–7C Is the value of the integral 1 dQ/T the same for all
processes between states 1 and 2? Explain.
