**__Boyle’s Law:__** states that the volume of a fixed mass of gas varies inversely with the pressure at constant temperature. In other words this means if the volume decreases then the pressure of the gas will increase.
 * __ Boyle __**

Robert Boyle in 1662 discovered that gas pressure and volume are related to one another mathematically. This discovery was brought on by noticing when the pressure of a gas is doubled, and the temperature is kept at a constant, the volume reduces by one-half. A theory that supports this law is the kinetic- molecular theory. The pressure of a gas is caused when the gas particles come in contact with the walls of the container. So when the volume is reduced there will be more molecules per unit of volume and this will cause more collisions with the walls of the container. Subsequently the pressure will increase.

Boyle’s Law is illustrated as: **PV=k** Meaning one would multiply the pressure by the volume and receive the constant.
 * P=pressure
 * V=volume
 * k= is the constant

So solve pressure-volume problems one can use the equation: **P1V1=P2V2** P1 and V1 are considered the initial conditions While P2 and V2 signify a different set of conditions
 * P1=first measurement for pressure
 * V1= first measurement for volume
 * P2= second measurement for pressure
 * V2= second measurement for volume

This picture shows how if the volume decreased the pressure inside the container would increase.
