Analytic Essay

My lab on Boyle's Law was a very good one. It was exactly what I thought it would be and the results turned out to be very close to my hypothesis. My experiment utilized the formula of Boyle's Law. This formula basically says that there is an inverse relationship between pressure and volume. My experimented illustrated this. When I went down to deeper depths where the pressure is greater, the air bubble in my container shrank. This shows the inverse relationship which is the greater the pressure, the smaller the bubble becomes. In other terms, this means that when you descend to greather depths, the air bubble size gets smaller. This statement is the basis of Boyle's Law. The formula for Boyle's Law is P1 x V1 = P2 x V2. P stands for the pressure and V stands for the volume. This means that the pressure of the first depth multiplied by the volume at that depth is equal to the pressure of the second depth multiplied by the volume at the second depth. Here is an example:
1 x 13.5 = 4/3 x Y
multiply each side by 3/4
10.125 cm. = Y
If I plug the value for Y back into the formula:
1 x 13.5 = 4/3 x 10.125
13.5 = 13.5
This formula says that if the size of the air bubble at one atmosphere of pressure is 13.5 cm., it will be 10.125 cm. at 1 1/3 atmospheres of pressure. As the pressure increased from one to 1 1/3 atmospheres, the size of the air bubble decreased.
These results and Boyle's Law are very relevant to scuba diving safety. When I go down to the bottom of the pool, I am under more pressure than I am at the surface. With greater pressure, I need denser air with a higher concentration of oxygen. If I had a hose up to the surface and breathed surface air at 30 feet deep, for example, the air from the surface would be less dense and have a lower concentration of oxygen than I need at my current depth. When you descend, the air in your tank becomes compressed, or denser, and there is a higher concentration of oxygen in a smaller volume. So Boyle's Law tells me that I must breathe compressed air at greater pressure. Because the volume of air decreases at greater depths, this means that I will empty my scuba tank faster at greater depths. I need to be aware of how much air I have and how fast I'm using it, especially at great depths.
