(273 K), the volume should decrease; this fraction must be. So
Or you can use the formula:Another Example
The volume of a gas is 27.5 mL at 22.0°C and 0.974 atm. What will the volume be
at 15.0°C and 0.993 atm?
Using the combined gas law,Pressure Versus Temperature (Gay-Lussac’s Law)
At Constant Volume, the Pressure of a Given Mass of Gas Varies Directly
with the Absolute Temperature. Then
