A large cylindrical tank contains 0.850 m3 of nitrogen gas at 28.0 ∘C and 8.50×103 Pa (absolute pressure). The tank has a tight-fitting piston that allows the volume to be change What will be the pressure if the volume is decreased to 0.450m ^3 and the temperature is increased to 165 C?
A tank with a constant volume of 5.89 m3 contains 15 moles of a monatomic ideal gas. The gas is initially at a temperature of 300 K. An electric heater is used to transfer 56500 J of energy into the gas. It may help you to recall that CVCV = 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....
A young male adult takes in about 5.80 x 10-4 m3 of fresh air during a normal breath. Fresh air contains approximately 21% oxygen. Assuming that the pressure in the lungs is 1.03 x 105 Pa and air is an ideal gas at a temperature of 310 K, find the number of oxygen molecules in a normal breath.
