An ideal gas is compressed adiabatically from an initial volume V to a final volume aV and a work W is done on the system in doing so. The final pressure of the gas will be

The exhaust nozzle of a jet engine expands air at 300 kPa and 180C adiabatically to 100 kPa. Determine the air velocity at the exit when the inlet velocity is low and the nozzle isentropic efficiency is 96 percent.

As shown in the figure, a container with a moveable piston and containing a monatomic ideal gas in an initial state A undergoes an isovolumetric, then an isothermal, and finally an isobaric process to complete the cycle. P (atm) C V (L) 0 When the gas is in the initial state, the volume is 7.00 L, the pressure is 3.00 atm, and the temperature is 350 K. The gas is first warmed at constant volume to a pressure of 4 times the initial value (state B). The gas is then allowed to expand isothermally to some new volume (state C). Finally it is compressed isobarically to its initial state. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) Find the number of moles of the gas. moles (b) Find the temperature of the gas at state B (in K). K (c) Find the temperature of the gas at state C (in K). K B A

In a quasi-static isobaric expansion, 500 J of work are done by the gas. If the gas pressure is 0.80 atm, what is the fractional increase in the volume of the gas, assuming it was originally at 20.0 L?
