Question

Help! I would really appreciate it!! Thank you!!

1) A reference state is usually chosen at a specific temperature, pressure, and state of aggregation (phase) to tabulate measured changes in U or H.

True or False

2) It is possible to determine the absolute value of the specific internal energy U or the specific enthalpy H for a process material at a given state.

True or False

3) Which property of a system component depends only on the state of the system (temperature, pressure, phase, and composition), and not on how the system reached the state?

(Choose the best answer)

- Specific enthalpy

- Reference state

- State property

Explanation / Answer

1) True - (U and H are the state function that is their value depends only on state of system.)

2) True - ( internal energyU and enthalpy H are the state function therefore their values depend on stae of the substancre.)

3) Specific enthalpy - (enthalpy H is state function their values depend on stae of the substance and not depend upon the how the state is achive.)
