Air at a mountain top has pressure 0.80 times that at the bottom. Its temperatures are 240 K at the top and 300 K at the bottom. For ideal air of the same composition, top-to-bottom density ratio is:

Options:

Answer:

Solution:

$\frac{ρ _{t}}{ρ _{b}} = (\frac{P _{t}}{P _{b}}) (\frac{T _{b}}{T _{t}})$ .

$\frac{ρ _{t}}{ρ _{b}} = 0.80 (\frac{300}{240}) = 1.00.$
