Boyle's Law
By: Connor Wagner
Concept of Boyle's Law
Boyle's Law states that the product of the pressure and volume for a gas is a constant for a fixed amount of gas at a fixed temperature. Written in mathematical terms, this law is
P V = constantThe use in Boyle's law
A common use of this law is to predict how a change in pressure will alter the volume of the gas or vice versa. Such a problem can be regarded as a two state problem: the initial state (represented by subscript i) and the final state (represented by subscript f). If a sample of gas initially at pressure Pi and volume Vi is subjected to a change that does not change the amount of gas or the temperature, the final pressure Pf and volume Vf are related to the initial values by the equation
Pi Vi = Pf VfSome pictures of Boyle's Law
