Treat the atmosphere as an ideal gas with a uniform temperature of 200 K. Find the density at 20 km.
R= 260 N*m/(kg*k)
g= 3.92 m/s^2
rho(0)= 0.015 kg/m^3
The Attempt at a Solution
I found the pressure at ground level using P=rho*R*T
P=(0.015 kg/m^3) (260 N*m/(Kg K)) (200 K) = 780 N/m^2
I'm not sure how to proceed from here.
