Gas Laws

Question 1

Boyles Law

Answer 1

At a constant temperature, absolute pressure and the volume of gas are inversely proportional.

P1V1=P2V2

Question 2

Charles’/Gay-Lussac’s Law

Answer 2

At a constant pressure, the volume of a gas is directly proportional to the change in absolute temperature
V1/T1=V2/T2

OR

At a constant volume, the absolute pressure will change in proportion to the absolute temperature
P1/T1=P2/T2

Question 3

General Gas Law

Answer 3

Boyle, Charles, and Gay-Lussac’s laws demonstrate that temperature, volume, and pressure affect a gas in such a way that a change in one factor must be balanced by corresponding change in one or both of the others

Question 4

Dalton’s Law

Answer 4

States that the total pressure exerted by a mixture of gases, is equal to the sum of the pressures of each of the different gases, making up the mixture, with each gas acting as if alone was present and occupied the total volume.

Question 5

Henry’s Law

Answer 5

The amount of any given gas that will dissolve in a liquid at a given temperature is directly proportional to the partial pressure of that gas.

Question 6

Compute Absolute pressure

Answer 6

(depth+33)/33

Question 7

Compute partial pressure

Answer 7

(Depth+33)/33 x %gas = pp in ATA
