Answer:
Explanation:
The altitude is irrelevant, except as needed to define the pressure. In this example all three parameters of the Ideal Gas Laws are changing. We set up the equation to solve for the desired final volume. Start with the Ideal Gas Law:
P
⋅
V
=
(
n
⋅
R
⋅
T
)
where the number of moles of gas and the gas constant do not change.
