Question

Problem 1 (20 points): For each of the following statement, choose "T (True) or "F" (False) 1. A heat engine with a 100% efficiency is impossible to build because it violates the first law of thermodynamics. 2. Entropy generation is a state property 3. If a process is both adiabatic and reversible, then the process is also isentropic. 4. For an expansion process, the boundary work is positive. 5. Entropy per unit mass and specific heat have the same dimension. 6. The compressibility factor Z-Pv/(RT) for an ideal gas is always 1. chanical energy to flow energy 8. It is possible to compress an ideal gas isothermally in a piston-cylinder device. 9. Consider two identical fans, Fan A at sea level and Fan B on top of a high mountain, running at identical speeds. The mass flow rate of Fan A is higher than that of Fan B 10.One incorrectly uses the "ratio of the volume of the saturated vapor to the total volume" to calculate the quality, so his/her result is larger than the real quality.

B - True( for a microscopic perceptive, entropy is a state property)

C- True(yes it is)

D- False

E- True

F - False
