the+gas+laws

There are five major gas laws that can be used to predict the behavior of a gas sample under changing conditions such as temperature, pressure, volume, and amount.

The first law is **Boyle's Law**, which relates the pressure of a gas to its volume.
 * As the volume of a gas sample decreases, the pressure exerted by that gas increases (an opposite effect, called an inversely proportional relationship).
 * Assume that the temperature and amount of gas does not change.
 * Here is a nice [|visual of Boyle's Law.]

The relationship between gas temperature and its volume is given in **Charles' Law**.
 * As the temperature of a gas sample increases, the volume of the gas sample increases (a directly proportional effect).
 * Assume that the pressure and amount of the gas does not change.
 * Check out this [|visual for Charles Law.]



These two laws are actually what makes up the [|Combined Gas Law].

The relationship between the amount of gas in a sample and its volume is called **Avogadro's Law**.
 * As the amount (metric unit: the mole) of a gas is increased, the volume it occupies also increases proportionally.
 * Assume that the temperature and pressure of the gas does not change.
 * The best visual for this law is a simple one - imagine inflating a balloon. More air into the balloon causes it to get larger in size.
