A bag of potato chips contains 585 mL of air at 25°C with a pressure of 765 mm HG. What will be its volume at the top of the mountain where the pressure is 442 MM Hg and the temperature is 5.0°C

944.55mL

Explanation:

Data obtained from the question include:

V1 (initial volume) = 585 mL

T1 (initial temperature) = 25°C = 25 + 273 = 298K

P1 (initial pressure) = 765 mmHg

V2 (final volume) =?

P2 (final pressure) = 442 mmHg

T2 (final temperature) = 5°C = 5 + 273 = 278K

Applying the general gas equation P1V1/T1 = P2V2/T2, the final volume at the top of the mountain can be obtained as follow:

P1V1/T1 = P2V2/T2

765 x 585/298 = 442 x V2/278

Cross multiply to express in linear form as shown below:

298 x 442 x V2 = 765 x 585 x 278

Divide both side by 298 x 442

V2 = (765 x 585 x 278)/(298 x 442)

V2 = 944.55mL

Therefore, the volume at the top of the mountain will be 944.55mL

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
