| | Dalton's law and divingWritten by Jakob Jelling
Dalton's law refers to effects which partial pressure might have on divers. This law says that pressure of mixed gases is equal to pressure produced by individual gas. It can also be explained by saying that total pressure of a mixture of gases equals sum of partial pressures of gases which are part of it.This means that number of molecules present in total volume of a gas is proportional to number of molecules present on each one of gases which compose it. This way, while total gas pressure increases as a diver goes deeper into water, partial pressure of each gas involved increases as well, and effects which might cause on divers body also increases with it. For example, air is a mixture of gases which contains about 80% of nitrogen and 20% of oxygen although it also includes small amounts of other gases as well. According to Dalton's law, partial pressure exerted by nitrogen and by oxygen which make air will be equal to total pressure of air; and they will increase simultaneously.
