A gas at a pressure of 2.50 atm undergoes a quasistatic isobaric expansion from 3.30 to 5.20 L. How much work is done by the gas (in J)?

For water with pressure of P=8MPa and secific volume v=0.023525 m3/kg, (5) Find the the corresponding temperature T___________ºC

The piston of a vertical piston-cylinder device containing a gas has a mass of 50 kg and a cross- sectional area of 0.04 m2, as shown in the figure. The local atmospheric pressure is 0.97 bar, and the gravitational acceleration is 9.81 m/s². What is the pressure inside the cylinder?

A container holds 75.2 liters of Oxygen at 271.4K and a pressure of 3.87 atmospheres.  How much heat is required to raise the temperature of this gas to 296.4K, holding the volume constant?  Give your answer in kJ.  Treat the gas as an ideal gas.  Note:  It is understood that your answer is in units of kilo-Joules, however do not explicitly include units in your answer.  Enter only a number.  If you do enter a unit ("kJ" in this case), you answer will be counted wrong.

Given the following property data for H,0 designate the region in T-v or P-v space (i.e., compressed liquid, liquid-vapor mixture, superheated vapor, etc.) and find the value(s) of the requested property or properties. Use the tables in Appendix D or the NIST database as necessary. Provide units with your answers.

For a gas of volumes Vi = 9.50  10-4 m3 and Vf = 1.40  10-4 m3 and pressures Pi = 2.00  106 Pa and Pf = 2.05  107 Pa, answer the following.For an isobaric process at Pi, find the internal energy change of the gas during this process.For an isovolumetric process at Vi, find the internal energy change of the gas during this process.
