Q

Boyle’s Law (Mariotte’s Law)

A

the absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system;

Q

Charles’ Law

A

The volume of a given mass of an ideal gas is directly proportional to its temperature on the absolute temperature scale (in Kelvin) if pressure and the amount of gas remain constant; that is, the volume of the gas increases or decreases by the same factor as its temperature;

Q

Avogadro’s Law

A

equal volumes of all gases, at the same temperature and pressure, have the same number of molecules;
for a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant;
