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

Question

what will be the new volume of the bag of chips?

show all work please!!

Answer 1

Hi, Arshi,

The volume of a gas is directly proportional to the temperature. We will assume the presure is constant (ambient pressure before and after). This is Charle's Law and it can be stated as:

V2 = V1(T2/T1)

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

V2 = 285ml

Answer 2

Charles's Law: V/T = V'/T'.

( .250 L / 292 K ) = ( V' / 333 K )

( .250 L / 292 K ) ( 333 K) = V' or ( 333 K / 292 K )( .250 L ) = 1.14 ( .250 L )

V' = 0.2851 L = 285.1 mL and therefore occupies more VOLUME
