A gas at 5 degrees celsius occupies a volume of 7.5 L. What volume will the gas occupy at 100 degrees celsius?

10.06L

Explanation:

Data obtained from the question include:

T1 (initial temperature) = 5°C = 5 + 273 = 278K

V1 (initial volume) = 7.5L

T2 (final temperature) = 100°C = 100 + 273 = 373K

V2 (final volume) = ?

Using Charles' law equation V1/T1 = V2/T2, the final volume can simply be obtain as illustrated below:

V1/T1 = V2/T2

7.5/278 = V2/373

Cross multiply to express in linear form

278 x V2 = 7.5 x 373

Divide both side by 278

V2 = (7.5 x 373) / 278

V2 = 10.06L

The final volume of the gas is 10.06L
