semi - finals

Small container

Lesser volume, higher pressure

Big container

Greater volume, lower pressure

Gas units

Atm, torr, N/m2, pa, mmHg, psi

Compressible

Gas can still be pumped inside a balloon even though it is already inflated

Boyle’s Law

Volume of a gas is inversely proportional to pressure

Charles’ Law

Volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant
