Consider a day in the physics lab room with room temperature of 20 0C and pressure of 1.0 atm. A container of 3.5 L is left open to the air for a long time. The container is then sealed and place on a Bunsen burner until its temperature reaches 95 0C. It is then open. How many moles of air escape?
when the temperature of an automobile tire is 20 degrees c, the pressure in the tire reads 29 psi on a tire gauge. (the gauge measures the difference between the pressures inside and outside the tire.) what is rhe pressure when the tire heats up to 39 degrees c while driving? you may assume that the volume of the tire remains the same and that the atomspheric pressure is a steady 14 psi.
at a birthday pool party, the temperature is 27.50 degrees celcius and the atmospheric pressure is 761.4 mmHg. one of the decoration helium baloons has a volume of 6.25 L. what would be the volume of the balloon if it were submerged in a swimming pool to a depth where the pressure is 922.3 mmHg and the temperature is 25.35 degrees celcius.
