Question I
1. Clausius looked at a heat engine along with it’s connected thermal reservoirs as one
single closed system. True or False
2. The Clausius inequality is
. True or False
3. If cyclic integral of anything is zero, then that anything has to be a change in
property. True or False
4. Entropy change between any two states can be defined as follows. True or False
5. By studying the case of internally reversible isothermal process the above integral
can be simplified resulting in the observation that entropy cannot decrease due to
heat loss. True or False
