Question

On a hot day, you may have noticed a bag of potato chips seems to “inflate.” If I have a 250. mL bag at a temperature of 292 K, and I leave it in my car that reaches a temperature of 333 K, what will be the new volume of the bag of chips?

Answer 1

The fact that the problem states "a bag of potato chips seems to 'inflate'" suggests that the bag is capable of expanding, and so since that's the case, we'll assume the pressure remains constant. Then we are dealing with Charles' Law.

V1/T1 = V2/T2

V1 = initial volume = 250. ml

T1 = initial temperature = 292K

V2 = final volume = ?

T2 = final temperature = 333K

(250.ml) / 292K = V2 / 333K

V2 = 285 mls (3 sig figs)
