A vacuum chamber does not produce a true vacuum, but can produce a very low pressure of N/m2 at a temperature of . How many molecules per cubic centimeter remain in the vacuum chamber?
A company advertises that it delivers helium at a gauge pressure of Pa in a cylinder of volume 43.8 L. How many balloons can be inflated to a volume of 4.00 L with that amount of helium? Assume the pressure inside the balloons is Pa and the temperature in the cylinder and the balloons is .
A bicycle tire contains 2.00 L of gas at an absolute pressure of N/m2 and a temperature of . An amount of gas that has a volume of cm3 at atmospheric pressure is released from the tire, having negligible effect on the tire’s temperature and volume. What is the pressure of the gas in the tire after the gas is removed?
