Laws

Question 1

Boyle’s law

Answer 1

For a fixed amount of gas, the pressure of gas is inversely proportional to the pressure of the gas at a constant temperature

Question 2

Charle’s law

Answer 2

For a fixed amount of gas, volume of gas is directly proportional to the temperature in absolute temperature scale. Provided that the pressure remains constant.

Question 3

Gay Lussac’s law

Answer 3

For a fixed amount of gas in a rigid vessel, pressure exerted by the gas is directly proportional to its temperature

Question 4

Avogadro’s law

Answer 4

Equal volumes of gas contain equal number of molecules at the same temperature and pressure.

Question 5

Dalton’s law of partial pressure

Answer 5

According to this law, in a mixture of “non-reacting gases”, the total pressure is equal to the sum of partial pressure of each gas present in the mixture.

Question 6

Graham’s law of Diffusion

Answer 6

According to this law, the rate of change of diffusion or effusion is inversely proportional to the square root of the density of the gases.
