Q

states that equal volumes of all ideal gases (at the same temperature and pressure) contain the same number of molecules.

A

2
Q

states that equal pressure is inversely proportional to volume (when temperature is constant).

A

Boyle’s Law

3
Q

states that volume is proportional to temperature (when pressure is constant). Remember that temperature must be measured in Kelvin.

A

Charles’s Law

the same composition; i.e., the same proportions by mass of constituent elements.

A

Law of Definite Proportions
