Charles's Law The following law was created by Charles, and was published in 1802 by James Gay-Lussac. He himself discovred the law in 1787 and the following law was named after him as he had discovered it.

What is Charles's law? Well it states that volume and temperature are directly proportional, meaning if one is increased the other decreases, since the pressure is constant at all times. This following law is explained by the equation: V/T=k where as K is the constant, with V the volume and T the temperature. Then there are the 3 equations that come with the following law" V1/T1=V2/T2, V1/T2=V2/T1 and V1*T1=V2*T2 an example would be one of the following, For example the original volume is 35mL, having the temp be 36 degree, and the new temp is 45 degrees and we have to find the new volume, how to solve it? Well lets see using V1/T1=V2/T2 35/36=?/43 so using cross multiplication, 36?=1505 divide both sides by 36 ?=41.9mL For a great animation and to understand this law better Please visit this following Link http://www.chm.davidson.edu/ChemistryApplets/GasLaws/CharlesLaw.html Back to main page
