Gas Laws and Scuba Diving

Combined Gas Law

Combined gas law connects to scuba diving because it shows that the deeper the diver goes the more the pressure of the gas in the tank increases. It also shows that the deeper the divers go the temperature and volume decrease.

If the temperature is high the pressure will also be high. If the volume is high the pressure will be low. That means that when going deeper the temperature and pressure will be high. When the diver isn't very deep the volume will be high and the pressure will be low.

combined gas law is a combination of the gay-lussac, boyel and charles law. The product of pressure, volume and absolute temperature is equal to K which is a constant.

Equation: P1V1/T1=P2V2/T2

Dalton Law

Dolton's law is connected to scuba diving because the air that is in the tank is a mixture of 21% of oxygen and 78% nitrogen. To find the total pressure you would need to know the pressure of the oxygen and add it to the pressure of the nitrogen.

If the oxygen that is being inhaled has a pressure of above 1.6 atm(atmospheric) it can be poisoning. Dolton's law can be used to calculate how deep the diver can go without having a pressure of 1.6 or higher.

Dalton's Law is a gas law that states that the total pressure of a substance that is made up of different gasses is the sum of all of the pressure of each of the different gasses.

Equation: PTotal = P1 + P2 + P3 . . .

Gay-Lussac Law

Scuba diving connects to Gay-Lussac's Law because it helps determine how much air you have left that can be used safely. The heating and cooling of the air in the tank has an impact on the air that is safe to inhale. When the tank is full the pressure and temperature increase

When the tank is filled more oxygen and nitrogen molecules are added which makes the pressure and temperature increase.

Gay-Lussac Law is a law that states that if the volume is constant, the pressure of a certain amount of gas is directly proportional to the temperature.

Equation:P1/T1 = P2/T2

Henry Law

Henry's law is connected to scuba diving because it shows that when the pressure increases the gas that is dissolved in the divers blood will also increase. If the diver stays too deep for too long more nitrogen will dissolve in the blood of the diver.

Henry's Law is a law that states that the mass of a gas that was dissolved in liquid is proportional to the pressure of the gas above the liquid.

Equation: Cg=KPg

Charles Law

Charles's law is connected to scuba diving because it is used to explain why divers wear dry suits. The reason that they wear it is because it keeps them warmer in the water by "trapping a layer of air between the diver and the suit". They are able to add and release air in their suits which help change the gas volume of the suit.

Charles Law is a law that states that if the pressure is constant then the volume of gas would be proportional to each other.

Equation: V1/T1 = V2/T2

Boyel's Law

Scuba Diving can be related to boyel's law because it is used to explain why diver should not hold their breath when diving. When the diver inhales the air from the tank at the surface the pressure in their lungs will be 1 atm(atmospheric pressure). If the diver continues to go deeper down while holding their breath their lung volume will increase. This could be very dangerous for your lungs.

This could be connected to how if you were to push an object down in the bath tub filled with water if you let go of the object it will float back up. This is because initially when pushing it down there is a lot of pressure and the object fills up with the water.

Boyel's law is a law that explains that as that pressure of the gas increases the volume of the container decrease. When the temperature is at a constant the the volume and pressure and inversely proportional.

Equation: P1V1 = P2V2
