Air that initially occupies 0.72 m3 at a gauge pressure of 140 kPa is expanded isothermally to a pressure of 101.3 kPa and then cooled at constant pressure until it reaches its initial volume. Compute the work done by the air. (Gauge pressure is the difference between the actual pressure and atmospheric pressure.)

An ideal gas with γ = 1.4 occupies 6.0 L at 300 K and 100 kPa pressure. It is compressed adiabatically until its volume is 2.0 L. It's then cooled at constant pressure until it reaches 300 K, then allowed to expand isothermally back to its initial state. a.) Find the net work done on the gas. b.) Find the minimum volume reached.

An ideal gas with γ=1.4 occupies 5.0 L at 300 K and 120 kPa pressure and is heated at constant volume until its pressure has doubled. It's then compressed adiabatically until its volume is one-fourth its original value, then cooled at constant volume to 300 K , and finally allowed to expand isothermally to its original state. Find the net work done on the gas. W= ___J

An automobile tire is filled to a gauge pressure of 195 kPa when its temperature is 20°C. (Gauge pressure is the difference between the actual pressure and atmospheric pressure.) After the car has been driven at high speeds, the tire temperature increases to 55°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. kPa (b) Calculate the gauge pressure if...

A rigid container with a volume of 2 m3 initially contains 0.05 m3 of liquid and 1.95 m3 of vapor at 125 kPa. Heat is transferred from a 3000C source to the contents of the vessel until the pressure in the container reaches 4 MPa. The contents of the vessel are now cooled in a surrounding temperature of 250C until the contents reach its initial state. Determine total entropy generated (Sgen) during the cycle.

Question 6 Gauge pressure is the difference between actual pressure (or absolute pressure) at a point of a system, and atmospheric pressure. Essentially it is pressure within a fluid, either liquid or a gas, at depth. Car tyre pressure is reported as gauge pressure, since the compressed air inside the tyre is a fluid, and is the difference between actual pressure of the tyre and atmospheric pressure. Answer the following questions: a) What is the absolute pressure in the tyre,...
