Apiston contains 160 moles of an ideal monatomic gas that initally has a pressure of 1.9 × 105 pa and a volume of 3.6 m3. the piston is connected to a hot and cold reservoir and the gas goes through the following quasi-static cycle accepting energy from the hot reservoir and exhausting energy into the cold reservoir.

the pressure of the gas is increased to 4.9 × 105 pa while maintaining a constant volume.
the volume of the gas is increased to 10.6 m3 while maintaining a constant pressure.
the pressure of the gas is decreased to 1.9 × 105 pa while maintaining a constant volume.
the volume of the gas is decreased to 3.6 m3 while maintaining a constant pressure.

it may you to recall that cv = 12.47 j/k/mole and cp = 20.79 j/k/mole for a monatomic ideal gas, and that the number of gas molecules is equal to avagadros number (6.022 × 1023) times the number of moles of the gas.

Which statement is best supported by the information in the chart? wave y is moving the fastest. wave x is moving the fastest. all of the waves are moving at the same speed. all of the waves have the same value of wavelengths per second.

The flame produced by the burner of a gas (propane) grill is a pale blue color when enough air mixes with the propane (c3h8) to burn it completely. for every gram of propane that flows through the burner, what volume of air is needed to burn it completely? assume that the temperature of the burner is 195.0°c, the pressure is 1.05 atm, and the mole fraction of o2 in air is 0.210.
