1.) The pressure in an automobile tire was 1.o atm at 21 C. After driving for an hour, the tire heated up to 55 C. Assume that the tire remained at constant volume and no gas escaped from the tire.
Calculate the pressure of the tire at 55 C.
2.) The helium inside a balloon has a volume of 1.5 liters when confined under a pressure of 1.o atm and a temperature of 25 C. The balloon floats up into the sky where the pressure is 0.95 atm and the temperature is 20 C.
Calculate the volume of the balloon at 20 C and 0.95 atm.
Calculate the pressure of the tire at 55 C.
