Question

at 10°c the gas in a cylinderhas a volume of 0.250 l. the gas is allowed to expand to 0.285 l .what must the final temperature be for the pressure to remain constant ?

Answer 1

Using Charles' law (V1/T1 = V2/T2), we substitute values in where
T1=10
T2=?
V1=.250
V2=0.285
Just rearrange to solve for T2, and the answer is 11.4 C
Note the we do not have to convert the temperature into kelvins when using Charles' Law.
