Gas Laws

Question 1

Boyle’s Law

Answer 1

If the temperature is kept constant the volume of a given gas will vary inversely to the absolute pressure.

Formula: P1xV1 =P2×V2

Question 2

Charles Law

Answer 2

The amount of change is either volume or pressure is directly related to the change in the absolute temperature.
Formula: P1xT2=P2xT1 (V constant)
V1xT2=V2xT1 (P constant)

Question 3

Daltons Law

Answer 3

The total pressure exerted by a mixture of gases is equal to the sum of the pressure of each gas making up the mixture.
Formula: Total pressure = PP1+PP2+PP3

Question 4

Henry’s Law

Answer 4

The amount of gas which can be dissolved in a liquid at a given temperature is directly proportional to its partial pressure.
Formula: 1 liter of gas in solution at 1 ATA, we would have 5 litres of gas in solution at 5 ATA.

Question 5

General Gas Law

Answer 5

The combination of the gas laws in predicting behaviour of gas due to variable Pressure, Volume or Temperature.

Question 6

Nitrogen is how many more times soluble in fat than water?

Answer 6

5 times more soluble.
