COMBINED GAS
LAW
"The combined gas law states
that the product of the pressure
and volume of a fixed amount of
gas is directly proportional to its
Kelvin temperature. "

LAW
The mathematical equation
for the combined gas law is
SAMPLE PROBLEM
A sample of O2 (oxygen gas) occupies a volume of 1.62L at 755 mmHg
pressure and a temperature of 0 oC. What volume, in liters, will this gas
sample occupy at 725 mmHg pressure at 50 oC?

INTRODUCTION
- The ideal gas law gives the
relationships among the four
variables temperature,
pressure, volume, and molar
amount for a gaseous
substance at a given set of
conditions.
