In gas physics Kelvin temperature is directly proportional to?
|
Kinetic energy
|
|
|
Volume of a mass of gas at constant pressure is proportional to its absolute temperature
|
Charles Law
V1 x T2 = V2 x T1 |
|
|
At constant temperature the volume of a mass of gas is inversely proportional to the absolute pressure
|
Boyle's Law
P1 X V1 = P2 X V2 |
|
|
At a constant volume the absolute pressure on a given gas varies directly with the absolute temperature.
Doubling of temp will result in doubling of pressure. |
