Temperature at the foot of a mountain is 30^(@)C and pressure is 760 mm whereas at the top of the mountain these are 0^(@)C and 710 mm. Compare the densities of the air at the foot and at the to of the mountain.

Temperature at the foot of a mountain is 30^(@)C and pressure is 760 m

1.	Temperature at the foot of a mountain is 30^(@)C and pressure is 760 mm whereas at the top of the mountain these are 0^(@)C and 710 mm. Compare the densities of the air at the foot and at the to of the mountain.
Answer» <P> SOLUTION :`d=(PM)/(RT)`, Hence, `(d_(1))/(d_(2))=(P_(1))/(T_(1))xx(T_(2))/(P_(2))=(760 mm)/(303 K)xx(273 K)/(710 mm)=(0.964)/(1)`
