Explanation / Answer

1) The absolute pressure of water at constant density doubles when the depth is doubled (FALSE)

2) The temperature of a system is raised by 10oC. Thus temperature difference remains the same in kelvin units (TRUE)

3) The Patm in denver is lower than the Patm in aspen (TRUE)

4) Temperature and pressure are both intensive properties (TRUE)

5) In an adiabatic process, the temperature of the system remains constant (FALSE)

6) Pressure and volume are both extensive properties of a system (FALSE)

7) Energy can cross the boundaries of a closed system in the form of heat and mass (FALSE)

8) 1KWH is equal to 3600 KJ of energy (TRUE)

9) The work done by the system decreases the energy of the system (TRUE)

10) The total energy of a system remains unchanged during a cycle (TRUE)
