What are the three gas laws?

1. Boyle's Law - describes the inversely proportional relationship between the absolute pressure and volume of a gas, if the temperature is kept constant within a closed system. This is seen by the equation:

2. Charles' Law - At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature on the absolute temperature scale (i.e. the gas expands as the temperature increases). This is seen by the equation:

3. Gay Lussac's Law - The pressure of a fixed mass and fixed volume of a gas is directly proportional to the gas's temperature. This is seen by the equation:

In all cases, P means Pressure

T means Temperature

V means Volume

1 means the beginning amount

while

2 means the ending amount
