Choose the correct dropdown for each statement below concerning these variables in thermodynamics. Pressure is a  [ state or path ]  variable. Work is a  [ state or path ]  variable. Heat is a  [ state or path ]  variable. Entropy is a  [ state or path ]  variable

Describe the relationship between entropy and ability to do work. Be sure to include the terms, entropy, order, disorder, temperature, volume, and work in your answer.

Determine which of the following are true or false and explain your answer: a) During an isothermal process, the entropy of an ideal gas stays constant if there is a net change in either pressure or volume b) Entropy generation takes place when there are irreversibilities in a cycle. c) The lower the isentropic efficiency of a turbine, the more power it will generate with the same input stream and same output pressure.
