charles's law: the volume-temperature relationship.
a few years after robert boyle discovered his law, jacques charles generated his own law. charles's law states that the volume of a fixed mass of gas at constant pressure varies directly with the kelvin temperature. in other words, the volume of a gas at a constant pressure will change according to temperature.

//this is how charles's law is expressed//: V1/T1 = V2/T2

V1 = initial volume. T1 = initial temperature. V2 = final volume. T2 = final temperature.

a sample of neon gas occupies a volume of 752 mL at 25° celcius. what volume will the gas occupy at 50° celcius if the pressure remains constant?
 * here is an example problem:**

//converting from celcius to kelvin//: remember that in chemistry, you use kelvin instead of celcius. so, before we start our problem, lets convert our temperatures. all you have to do to convert our temperatures is to add 273 to each celcius temperature. so, 25° celcius + 273 = 298 K. and, 50°celcius + 273 = 323 K. now we can put these into our equation!

//now, fill in your variables with the given information//: V1 = 752 mL. T1 = 298 K. V2 = unknown. T2 = 323 K.

//isolating the unknown//: now we need to isolate our unknown, which is V2. we can change our equation around like this: __V1T2__ = V2 T1

//filling in the variables//: so now, fill in our newer equation with the correct information given for the variables.

__(752 mL Ne)(323 K)__ = 815 mL Ne. 298 K

here, our problem proves that a volume of gas increases as the temperature increases. [problem from page 372 in the chemistry textbook.]
