Gas Laws

Question 1

Boyle’s Law (Mariotte’s Law)

Answer 1

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;

Question 2

Charles’ Law

Answer 2

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;

Question 3

Avogadro’s Law

Answer 3

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;

Question 4

Gay-Lussac’s Law

Answer 4

for a given amount of gas held at constant volume, the pressure is proportional to the absolute temperature;

Question 5

Combined Gas Law / Ideal Gas Law

Answer 5

the ratio between the pressure-volume product and the temperature of a system remains constant;

Question 6

Universal Gas Constant

Answer 6

R = 8.3144621(75) J/K·mol
