Gas Laws Review

Flashcards covering Boyle's Law, Charles' Law, and Gay-Lussac's Law, including their definitions, constants, proportionalities, and formulas.

Boyle's Law

States that pressure and volume are inversely proportional when mass is constant. As pressure increases, volume decreases. Formula: P1V1 = P2V2 or P imes V = K.

Boyle's Law (Pressure and Density)

Under Boyle's Law, pressure and density are directly proportional; as pressure goes up, so does density.

Charles' Law

States that temperature and volume are directly proportional when pressure is constant. As temperature increases, volume increases. Formula: V1/T1 = V2/T2 or V/T = K.

Charles' Law (Temperature and Density)

Under Charles' Law, density is inversely proportional to temperature; as temperature goes up, density goes down, and vice versa.

Gay-Lussac's Law

Also known as the pressure and temperature law, it states that pressure and temperature are directly proportional when mass is fixed and volume is constant. As temperature increases, pressure increases. Formula: P1/T1 = P2/T2.

Boyle's Law: How to identify when to use it?

Use Boyle's Law (P1V1 = P2V2) when the question states that the mass of the gas and temperature are kept constant, and you need to calculate changes in pressure (P) and volume (V).

Charles' Law: How to identify when to use it?

Use Charles' Law (V1/T1 = V2/T2) when the question states that the mass of the gas and pressure are kept constant, and you need to calculate changes in volume (V) and temperature (T).

Gay-Lussac's Law: How to identify when to use it?

Use Gay-Lussac's Law (P1/T1 = P2/T2) when the question states that the mass of the gas and volume are kept constant, and you need to calculate changes in pressure (P) and temperature (T).
