Ideal gas law problems
A.) At the start of a trip, a driver adjusts the absolute pressure in her tires to be 2.79 105 Pa when the outdoor temperature is 284 K. At the end of the trip she measures the pressure to be 3.02 105 Pa. Ignoring the expansion of the tires, find the air temperature inside the tires at the end of the trip.
B.) Oxygen for hospital patients is kept in special tanks, where the oxygen has a pressure of 60.0 atmospheres and a temperature of 286 K. The tanks are stored in a separate room, and the oxygen is pumped to the patient's room, where it is administered at a pressure of 1.00 atmosphere and a temperature of 297 K. What volume does 2.00 m3 of oxygen in the tanks occupy at the conditions in the patient's room?
C.) Two ideal gases have the same mass density and the same absolute pressure. One of the gases is helium (He), and its temperature is 178 K. The other gas is neon (Ne). What is the temperature of the neon?

A.) At the start of a trip, a driver adjusts the absolute pressure in her tires to be 2.79 x 105 Pa when the outdoor temperature is 284 K. At the end of the trip she measures the pressure to be 3.02 x 105 Pa. Ignoring the expansion of the tires, find the air temperature inside the tires at the end of the trip.
