Initially 1.300 mol of an ideal gas in a container occupies a volume of 2.50 l at a pressure of 3.30 atm with an internal energy U1 = 592.8 J. The gas is cooled at a constant volume until its pressure is 2.00 atm. Then it is allowed to expand at constant pressure until its volume is 5.50 l. The final internal energy is U2 = 790.4 J. All processes are quasi static. Draw this process on a PV diagram. What is the work done by the gas?
Find the heat added during this process.
A rigid tank contains 1.40 moles of an ideal gas. Determine the number of moles of gas that must be withdrawn from the tank to lower the pressure of the gas from 27.2 atm to 5.90 atm. Assume the volume of the tank and the temperature of the gas re..
