Gas Laws Summary Notes

Boyle's Law:

• Inverse relationship between pressure ($P$) and volume ($V$).

• As pressure increases, volume decreases and vice versa.

• Formula: P1V1 = P2V2

Gay-Lussac's Law:

• Direct relationship between pressure ($P$) and temperature ($T$).

• As pressure increases, temperature increases.

Charles's Law:

• Direct relationship between volume ($V$) and temperature ($T$) when pressure is kept constant.

• As temperature increases, volume expands.

Avogadro's Law:

• Direct relationship between the number of moles ($n$) (quantity of gas) and volume ($V$).

• As the number of moles increases, volume also expands.

Ideal Gas Law:

• A summation of Boyle's, Gay-Lussac's, Charles's, and Avogadro's laws.

• Describes how gases behave under ideal conditions, often referencing Standard Temperature and Pressure (STP).
