In 1781 Jacques Charles discovered the quantitative between volume and temperature. His experiments revealed that all gasses expand when heated up to a certain temperature.

B. Charles Law As stated in the book: //The pressure of a fixed mass of gas at constant volume varies directly with the Kelvin temperature.// If the volume doubles and the pressure does not change, then the temperature has to double according to Charles Law. Math is opposite of Boyle’s Law, because they both increase or decrease. * another note, is that in all of the equations, the degrees are in Kelvin. K = 273 + C  Constant: Pressure __V1__ = __V2__ <-- Equation T1 T2 Sample Problem: A sample of neon gas occupies a volume of 752 mL at 25 C. What volume will the gas occupy at 50 C if the pressure ramians constant? Given: V1 of Ne = 752 mL T1 of Ne= 25 = 273 K = 298 K: T2 of Ne = 50 C + 273 = 323 K Unkown: V2 of Ne in mL So now you need to alegrbraically change the equation to isolate V2. It will look like this: V2 = __V1 T2__ = __(752 mL Ne) (323 K)__ = 815 mL T1 298 K we can see that the increase in temperature increased the volume, proving the law. main page!!
