# Scuba Diving and Charle's Law

## What is scuba diving?

Scuba diving is a sport in which divers use a tank of compressed air to be able to breathe underwater.In order to be certified in scuba diving, one as to be in good health (a.k.a non-serious medical problems).

## What is Charles' Law?

Charles' Law is the law of gas that deals with temperature and volume. It states that if all other variables are constant, the volume of a gas varies directly with the temperature of the gas. In simpler terms, if the temperature of a gas goes down, the volume of it goes up proportionally and vice versa. It is important to remember that when measuring the temperature, one should use the Kelvin scale to avoid negative volumes from occurring. This is because if you were to use the Celsius or Fahrenheit scale, there is a possibility of achieving a negative number. When you use Kelvin, it is impossible to ever reach a temperature below zero, so the volume can never be below zero as well.

## How do you use Charles' Law?

The equation used for Charles' Law is (V1/T1)=(V2/T2). V1 and V2 stand for volume one and volume 2, respectively. T1 and T2 stand for temperature one and temperature 2, respectively. When using these two equations, you take the initial volume and place it over the initial temperature, and then set that equal to the final volume over the final temperature. When looking for an unknown temperature or volume, you simply have to set that variable equal to x and cross multiply to solve for it.

## How do scuba diving and Charles' Law relate?

An example of Charles' Law in relation to scuba diving is a scenario in which a scuba tank in left in the trunk of a hot car in the tropical sun. The temperature of the tank would rise along with the pressure (volume would remain constant), which would eventually cause the tank to burst open. Another example of this is when a scuba tank is filled with air. When it is filled, the friction of air entering the cylinder heats things up from the inside out, which increases the volume of gas that the tank can hold.
