His oxygen is low, and because of the pressure of the water as the diver goes deeper and deeper than he might get hypoxia. The Gulf of Mexico is more commonly known as the dead zone. The reason for this nickname is because the oil spill was caused in this area.

Also because when there is a lot of oil in an area it causes hypoxia; this may cause deaths or severe damage. When looking for oil, the machines may have a hit the wrong spot which would cause an oil spill. Another reason for an oil spill would be if a ship or any other mean of transportation dropped oil.
The vehicle, a ship for example, would be sailing with a load of oil in its storage. The oil may be too heavy or it would leak of the ship, causing a deadly situation. The oxygen in the water can drastically change over time. The amount depends only on one thing, the temperature. If the temperature of the weather is hot than the oxygen will be lost. Therefore, the weather also affects the oxygen. On the other hand, if the temperature is cold then this will cause the waters temperature to drop. The colder the water the more oxygen the water will have.
A commonly used method by scientists is called titration. This method is used to determine the unknown concentration of a known reactant. For example, titration would help see how much oxygen is in the water because the precipitant would change colors, as in the project that is being done.
The dissolved oxygen kit consists of a nail clipper, a narrow glass tube, a stopper, a bottle, Sodium Thiosulfate, and three very important reagents. Each of the reagents is needed to complete the testing of oxygen correctly. The first reagent, Dissolved Oxygen 1 Reagent, is made out of manganous Sulfate. Manganous Sulfate is used in medicines, and actually many things used in everyday life.
Actually, this sulfate is most commonly used on plants. It is added to the soil to help increase the plants growth. Because these three substances are mixed to make the second reagent, there is a small amount of each. The third and last reagent is Dissolved Oxygen 3 Reagent. This reagent is made of Sulfamic Acid. This acid is also known as amidosulfonic acid.

The chemical formula for this molecular compound is H 3 NSO 3. Sulfamic acid is used a lot in dyes and in places or companies that deal with pigments and colors. In the Hach kit, the third reagent contained 1. Further exploration is going on. Scientists are trying to find a way to clean all the oil. This issue is taken very seriously. This will make the world a better place if everyone cares about the environment. Solubility is the ability of a substance to dissolve in water at a given temperature.
This means that according to the temperature the substance will dissolve either better or worse. When a solid is in water, it dissolves much quicker in warm water. Unlike solids, gases dissolve much faster in cold water. The oxygen level is than either increased or decreased by the temperature. Therefore, if the temperature is warm, the oxygen level would be lower. The reason solids dissolve better in warm water is because the molecules structure.

In a solid the molecules are tightly packed. This is why when warm water touches solids, the heat separates the molecules and makes them loose. So, when gases are touched by cold water, the gases particles are affected.
Gas particles are originally very loose. So, when the gases are in cold water they become even looser. The reason hot water does not affect the gas is because it is already arranged loosely, so only cold water will spread the gases even more. It is predicted that the water with the oil will leave a dramatic effect. When the oil is in the water, it's expected that the oxygen level will drop because the motor oil will block oxygen exchange from the air.
Also, the temperature of the water should become warmer when the oil is coated on the water. This is predicted because the oil is thick and will serve as a blanket. The results of this project showed that the container with oil had a much lower amount of oxygen. Through the entire time the tests were taken, the oxygen level was always lower than the container with only water.
Also the container that had oil in it was always warmer than the one with only water by a few degrees. The results of the project actually agreed with my hypothesis. In the container with oil there was a dramatic drop of oxygen.

Not only did the oxygen have a difference than the container with only water but so did the temperature. The container with oil was always a few degrees warmer. This was because the layer of oil served as an insulating blanket.
