Suppose that 292 moles of a monatomic ideal gas is initially contained in a piston with a volume of 1.34 m3 at a temperature of 588 K. The piston is connected to a hot reservoir with a temperature of 1385 K and a cold reservoir with a temperature of 588 K. The gas undergoes a quasi-static Stirling cycle with the following steps: The temperature of the gas is increased to 1385 K while maintaining a constant volume. The volume of the gas is increased to 4.18 m3 while maintaining a constant temperature. The temperature of the gas is decreased to 588 K while maintaining a constant volume. The volume of the gas is decreased to 1.34 m3 while maintaining a constant temperature. It may help you to recall that CV C V = 12.47 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. 1) What is the pressure of the gas under its initial conditions?

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 2.50 L and the pressure is initially 125 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 80.0 J of work is then done on the piston, compressing the gas (in other words, the gas does -80 J of work). The work is done very slowly so that the gas maintains a...

car has been driven at high speeds, the tire temperature increases
to 51°C.
(a) Assuming that the volume of the tire does not change, and
that air behaves as an ideal gas, find the gauge pressure of the
air in the tire.
