Question

Please answer True for each of the following statements (10 points) NO or False Statement True or False Entropy is a state function. decreases. No process is possible for which the total entropy change Every process proceeds in such a direction that the total entropy 3 associated with it is positive. 4 Carnot engine is one type of heat engine For two given heat reservoirs no engine can have a thermal efficiency higher than that of a Carnot engine. entropy change is zero. For any mechanically reversible adiabatic process, The maximum when the process is completely 7 reversible 8 The maximum work is obtained with Carnot engine 9 Entro is not conservative, not like ener 10 The rate of entropy generation reflects the irreversibility of the process.

Explanation / Answer

First four questions are answered with explanations.

1. True. the value of entropy depends on different satet of a system and not path by which it is calculated.

2. Entropy is the value which indicate wheather a process is spontaneous or not.

For a process to occur there must be positive change in entropy. So true

3. True, In thermodynamics, the thermal efficiency is a measure of a device that uses thermal energy

4. true A Carnot heat engine is an engine that operates on the reversible Carnot cycle.
