Pressure/Volume of Air Full Lab Write Up

Introduction:

According to Boyle’s Law, the volume of any given amount of gas held at a constant temperature varies inversely with the applied pressure. In other words, when the pressure increases the volume decreases. When pressure decreases, volume increases. This can be derived from the following equation:
P1 V1=P2 V2

The common use of this equation is to predict how a change in pressure or volume will alter the volume/pressure of the gas. Thus, the product of the initial volume and pressure is equal to the product of pressure and volume after a change in either pressure or volume under constant temperature.
