Chapter 2, Problem 12P

The pressure in an automobile tire depends on the temperature of air in the tire. When the air temperature is 25 ° C , the pressure gage reads 210 kPa. If the volume of the tire is 0.025 m³, determine the pressure rise in the tire when the air temperature in the tire rises to 50°C. Also, determine the amount of air that must be bled off to restore pressure to its original value at this temperature. Assume the atmospheric pressure to be 100 kPa.

The pressure in an automobile tire depends on the temperature of the air in the tire. When the air temperature is 25 °C, the pressure gage reads 210 kPa. If the volume of the tire is 0.025 m3, determine the pressure rise in the tire when the air temperature in the tire rises to 50 °C. Also, determine the amount of air that must be bled off to restore pressure to its original value at this temperature. Assume the atmospheric pressure is 100 kPa.

: A mass of gas has a temperature of 150°C and volume of 0.2 m3. The temperature is changed to 50°C but the pressure is unchanged. Determine the new volume.

Air is enclosed by a rigid cylinder containing a piston. A pressure gage attached to the cylinder indicates an initial reading of 25 psi. Determine the reading on the gage (in psi) when piston has compressed the air to one-third its original volume. Assume the compression process to be isothermal and the local atmospheric pressure to be 14.7 psi.
