At a height of 2 km the thermometer reads -3° and the barometer reads 600 mm Hg. At sea level the temperature is 27° and the pressure is 760 mm Hg. Ratio of density of air at 2 km with that at sea level is
Options:
Answer:
B
Solution:
= /, so is proportional to / ( in kelvin).
(2 km)/(sea level) = (600/270) / (760/300) = 2.222/2.533 = 0.877, about 0.88.
Ratio = 0.88 : 1.
The option 0.79 : 1 comes from using only the pressures (600/760).
Answer: (B).
