atm. Calculate the pressure of the compressed fuel-air mixture (assuming temperature and the amount of gas
remain constant).- If a gas is cooled from 333.0 K to 273.0 K at a constant volume, what would the final pressure be if the original
pressure was 780.0 mm Hg? - A bag of potato chips is packaged at sea level (1.00 atm) and has a volume of 315 mL. If this bag of chips is
transported to Denver (0.820 atm), what will the new volume of the bag be? Assume the temperature remains
the same. - Calculate the volume (in L) occupied by 2.12 moles of nitric oxide (NO) at 6.54 atm and 76°C.

Points to Consider
- As we studied gases in this lesson, we assumed that all gases exhibit ideal behavior (collisions between
particles are completely elastic, the particles do not attract or repel one another, and the volume of the gas
particles is negligible compared to the volume they occupy). If some of these assumptions were not quite true,
how would it affect the observed gas laws? - What properties of gases are affected by the speeds of the individual particles?
