The density of a gas can vary from near zero (in outer space) to greater than the density of some solids.
solving problems:
1. a kit used to fix flat tires consists of an aerosol can containing compressed air and a patch to seal the
hole in the tire. suppose 5 liters of air at atmospheric pressure (1 atm) is compressed into a 0.5 liter
aerosol can.
what is the pressure of the compressed air in the can? assume no change in temperature or mass.
you are looking for the pressure inside of an aerosol con
you are given initial volume (in liters), initial pressure (in atmospheres), and final volume.
use boyle's law, p1 v1 = p2 v2; rearrange variables to solve for p2.
2. a total of 0.50 l of o2is collected at a pressure of 300 mm hg. what volume will this gas occupy at sea
level (760 mm hg) at constant temperature and mass?
3. a total of 1.0 l of helium is stored at sea level (1013 mb). if the gas is carried to the top of mt.
washington (pressure = 800 mb), what volume will it occupy at constant temperature and mass?
pressure and temperature
