elp with the problem below and explain well, Im really struggling with understanding it. Thank you so much in advance! Commercial airliners cruise at about 10 km above sea level, where the air outside is mighty cold - let’s say -60°C. Nonetheless the airplane needs ventilating, with the plane does by taking in the outside air and compressing it. a. What is the temperature of air that’s been collected from outside the plane and compressed to the pressure found at sea level? Does this air require warming or cooling to keep the inside of the plane comfortable? b. What is the maximum relative humidity of air compressed to sea level pressure? Does this sound comfortable?

a. What is the temperature of air that’s been collected from outside the plane and compressed to the pressure found at sea level? Does this air require warming or cooling to keep the inside of the plane comfortable?
b. What is the maximum relative humidity of air compressed to sea level pressure? Does this sound comfortable?
c. Compute the temperature and relative humidity again, now assuming that plane is flying through a cloud containing condensed liquid water equal to 1% of the equilibrium vapor pressure. Comment on the magnitude of the changes.
