An automobile tire has a volume of 1.62 x 10-2 m3 and contains air at a gauge pressure (pressure above atmospheric pressure) of 166 kPa when the temperature is 0.00°C. What is the gauge pressure of the air in the tires when its temperature rises to 29.6°C and its volume increases to 1.68 x 10-2 m3? Assume atmospheric pressure is 1.01 x 105 Pa.

A welder using a tank of volume 7.50×10−2 m3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×105 Pa and temperature of 36.6 ∘C. The tank has a small leak, and in time some of the oxygen leaks out. On a day when the temperature is 21.6 ∘C, the gauge pressure of the oxygen in the tank is 1.95×105 Pa . A) Find the initial mass of oxygen. kg B) Find...

A steel tank contains 312 g of ammonia gs (NH3 with molar mass 17.0 g/mol) at a pressure of 1.43 x 106 and a temperature of 80.6oC. (a) What is the volume of the tank in liters? (b) Later the temperature is 69.5oC and the pressure is 0.960 x 106 Pa. How many grams of gas have leaked out of the tank? (Ignore the thermal contraction of the tank.)

A 0.2 m3 piston-cylinder initially contains 400 K air. A heavy frictionless piston maintains a pressure of 500 kPa abs. Then, a weakness in the cylinder wall blows out and creates a hole. Air escapes through the hole until the piston drops far enough to cover the hole. At that point, the volume is half the initial volume. During this process, 75 kJ of heat is transferred to the 100 kPa, 300 K surroundings. Using Cp = 1.005 kJ/kg-K and...

A welder using a tank of volume 7.90×10−2 m3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×105 Pa and temperature of 35.0 ∘C. Remember that the guage pressure of the gas in the tank is the difference between the absolute pressure of the gas inside the tank and the pressure outside the tank, in this case 1 atm. So the absolute pressure is equal to the guage pressure plus 1...

Air is contained in a rigid, well-insulated container of volume 3 m3. The air undergoes a process from an initial state with a pressure of 200 kPa and temperature of 300 K. During the process, the air receives 720 kJ of work from a paddle wheel. Model the air as an ideal gas with constant specific heats. Evaluate the specific heats at 300 K. Neglect changes in kinetic energy and potential energy. Determine the mass of the air in kg,...
