P1 x V1 = P2 x V2
P = pressure
V = volume
In Boyle's Law, the volume of the gas varies inversely with the pressure.
A sample of carbon dioxide occupies a volume of 3.5 liters at 125 kPA pressure. What pressure would the
gas exert if the volume was decreased to 2 liters?
(3.5)(125) = (2)(P2)
437.5 = 2x
V1/T1 = V2/T2
In Charles' Law, the volume of a fixed mass of the gas is directly proportional to its Kelvin temperature.
A sample of nitrogen occupies a volume of 250 mL at 25 degrees Celsius. What volume will it occupy at 95 degrees Celsius?
.25/298 = x/368 *
298x = 92
* don't forget to convert to Kelvin! Celsius + 273 = Kelvin
