Question

Answer the following questions [9 though 11]. There is no need to follow the formal solution procedure, but you must provide the appropriate justification using basic equation and /or property relations to obtain credit. There is no partial credit. Hydrogen treated as an ideal gas is flowing steadily through a compressor where the pressure is increased at a constant temperature (i.e., isothermal process). Neglecting kinetic and potential energy changes, what happens to the following quantities?

Enthalpy: Increases Decreases Remains constant

Density: Increases Decreases Remains constant

Heat Transfer: Positive Negative Zero
