The molar specific heat at constant volume of an ideal gas is equal to 2.5times the universal gas constant (8.314J/mol-K). When the temperature increases by 150K. Find the change in molar specific enthalpy.
A tank is full of oxygen (M-32 g/mol) and open at the top.
There is a frictionless nozzle near the bottom, the diameter of
which is so small compared with the diameter of the tank that
the velocity at the free surface is zero. There is no friction and
nonflow work. Assuming ideal gas behavior for both of
oxygen and air (M-29 g/mol), what is the velocity of the
steady flow out of the nozzle?

E3.1. You must use the property data from the tables in the Appendix of your text to do this problem.
The figure below illustrates a pressure cooker with the pressure relief valve removed.
atm- 100 kPa
V= 2 liter
bottom 5%
is filled with
liquid water .
The pressure cooker has an internal volume of V = 2 liters. Because the relief valve is removed, the
contents are initially at atmospheric pressure, Patm = 100 kPa. The pressure cooker contains water in a
two-phase state. The bottom 5% of the volume of the vessel is filled with liquid water while the
remainder of the vessel contains water vapor.
a) Determine the initial temperature of the water in the cooker.
b) Determine the quality and specific volume of the water initially in the cooker.
c) Sketch by hand a T-v diagram and label the initial state of the water (state 1).

The container is cooled by -440 KJ and the pressure drops to 1 bar. Calculate the mass of water in the container in kg. Neglect kinetic and potential energy changes. Note that the reported heat transfer is negative because energy is leaving the container. It is closed system As the container is rigid, the volume and total mass will stay the same between the initial and final state. This means that the specific volume of water will stay constant.
