Five kg of oxygen (O2), initially at 430°C, fills a closed,
rigid tank. Heat transfer from the oxygen occurs at the rate 425 W
for 10 minutes. Assuming the ideal gas model with k
= 1.350 for the oxygen, determine its final temperature, in
°C.
Can't seem to find the right equations to use for this one, so I'm getting pretty stumped. Any help would be greatly appreciated

A closed rigid tank contains 2 kg of water at 80 C and
quality of 0.5815. The tank is then heated until it contains
only
saturated vapor. How much heat (in kJ) is added to reach this
condition? Include a drawing and plot the process on a P-V
diagram.

Five lbs of propane is contained in a closed, rigid tank
initially at 80 lbf/in.2, 50°F. Heat transfer occurs
until the final temperature in the tank is 0°F. Kinetic and
potential energy effects are negligible.
Determine the amount of energy transfer by heat, in Btu.

A closed, rigid tank fitted with a paddle wheel contains 2.2 kg
of air, initially at 200oC, 1 bar. During an interval of 20
minutes, the paddle wheel transfers energy to the air at a rate of
1 kW. During this time interval, the air also receives energy by
heat transfer at a rate of 0.5 kW. These are the only energy
transfers. Assume the ideal gas model for the air, and no overall
changes in kinetic or potential energy....

An air compressor rapidly fills a 0.3m3 tank (there is no heat
transfer through the tank walls), initially containing air at 27
?C, 1 atm, with air drawn from the atmosphere at 27? ?C, 1 atm.
During filling, the relationship between the pressure and specific
volume of the air in the tank is pv1.4 = constant. You can
model the air as an ideal gas with constant specific heats at
300K.
Calculate (and show your work) the tank’s pressure and...

A closed, rigid tank is filled with water. Initially, the tank
holds 0.6 lb of saturated vapor and 6.0 lb of saturated liquid,
each at 212°F. The water is heated until the tank contains only
saturated vapor. Kinetic and potential energy effects can be
ignored.
Determine the volume of the tank, in ft3, the temperature at
the final state, in °F, and the heat transfer, in Btu.

Problem 3.034
A closed, rigid tank is filled with water. Initially, the tank
holds 0.4 lb of saturated vapor and 4.0 lb of saturated liquid,
each at 212°F. The water is heated until the tank contains only
saturated vapor. Kinetic and potential energy effects can be
ignored.
Determine the volume of the tank, in ft3, the
temperature at the final state, in °F, and the heat transfer, in
Btu.

A closed, rigid tank contains water initially at 250 °F with a
quality of 0.4. The tank is heated until the water reaches 290 °F.
Find the initial and final pressure, in lbf/in2 . Sketch the
process on P-υ and T-υ diagrams (be sure to include the vapor dome,
constant temperature and pressure lines, number your states, and
indicate the process direction with an arrow). Thermodynamic

A closed, rigid tank contains a two-phase liquid–vapor mixture
of Refrigerant 22 initially at -20°C with a quality of 47.50%.
Energy transfer by heat into the tank occurs until the refrigerant
is at a final pressure of 6 bar.
a) Determine the final temperature, in °C.
b) If the final state is in the superheated vapor region, at what
temperature, in °C, does the tank contain only saturated vapor?

One kilogram of Refrigerant 134a vapor initially at 2 bar and
20°C fills a rigid vessel. The vapor is cooled until the
temperature becomes -24°C. There is no work during the
process.
Let To = 20°C, po = 0.1 MPa and ignore the
effects of motion and gravity.
2. For the refrigerant, determine the change in exergy, in
kJ.
Note: for part 1: q=-98.086kj please find part two- the change
in exergy in kj
