Today is a beautiful day for a picnic in the mountains, so we seal our peanut butter sandwich in a plastic sandwich bag at the base of the mountain. The approximate volume of the sandwich bag not occupied by the sandwich is 200. mL. The pressure at the base of the mountain is 1.0 atm. If the pressure at the top of the mountain is 0.80 atm, what is the final volume (mL) of gas in our sandwich bag
A) 250 mL
B) 260 mL
C) 270 mL
D) 280 mL
E) None of the above

Using Boyle's Law (P1V1 = P2V2), where P1 = 1.0 atm, V1 = 200 mL, and P2 = 0.80 atm, we can solve for V2 = (P1V1)/P2 = (1.0 atm * 200 mL) / 0.80 atm = 250 mL.
