Hikers noticed that a sealed bag of potato chips puffs up when taken to the top of a mountain. Suppose that at the valley floor below, the air pressure is 1.0 atm, the temperature is 25°C, and the volume of the bag is 0.985 L. At the top of the mountain, the temperature is 22°C and the bag has puffed up to 1.030 L. What is the air pressure on top of the mountain? Type in your answer using the correct number of significant figures.

Use the combined gas law with temperatures in kelvin.

T1 = 25°C = 298.15 K
T2 = 22°C = 295.15 K

P2 = P1 V1 T2 / (T1 V2) = (1.0 atm)(0.985 L)(295.15 K) / (298.15 K)(1.030 L)
= 0.9467 atm ≈ 0.95 atm (2 significant figures)

Answer: 0.95 atm
