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^circ C and the volume of the bag is 0.985 L. At the top of the mountain, the temperature is 22^circ 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. Formula: (P_(1)V_(1))/(T_(1))=(P_(2)V_(2))/(T_(2)) square atm

To solve this problem, we can use the ideal gas law equation:
where:-
is the initial pressure (1.0 atm)-
is the initial volume (0.985 L)-
is the initial temperature (25°C + 273.15 = 298.15 K)-
is the final pressure (unknown)-
is the final volume (1.030 L)-
is the final temperature (22°C + 273.15 = 295.15 K)Plugging in the values, we get:
Solving for
, we get:
Therefore, the air pressure on top of the mountain is approximately 1.0 atm.
