1.A bicycle tire is filled to a pressure of 4.42 atm (65 psi) at a temperature of 12?C. If the temperature of the tire increases to 33?C, what is the pressure in the tire? Assume the volume of the tire is constant.2.If 8.5 g of oxygen gas (O2) is introduced into an evacuated 1.50 L flask at 22?C, what is the pressure inside the flask?3.A tightly sealed 4.0-L flask contains 884 mm Hg of N2 at 94.0?C. The flask is cooled until the pressure is reduced 442 mm Hg. What is the temperature of the gas?4.1. A bicycle tire is filled to a pressure of 4.42 atm (65 psi) at a temperature of 12°C.
