State
At constant volume, a fixed amount of gas has pressure directly proportional to its kelvin temperature.
Show
Heating a sealed, rigid canister raises the gas pressure inside in direct proportion to its kelvin temperature rise.
Watch for
This proportionality holds only for kelvin temperature — doubling a Celsius reading does not double the pressure.
