Temperature at the foot of a mountian 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 top of the mountain.

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

1.	Temperature at the foot of a mountian 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 top of the mountain.
Answer» `rho=(PM)/(RT)` Hence `(rho_(1))/(rho_(2))=(P_(1))/(P_(2))xx(T_(2))/(P_(2))` `therefore(760mm)/(303K)xx(273K)/(710mm)=(0.964)/(1)` `thereforerho_(1):rho_(2)=0.964:1`

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressyre and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas beheviour as compared to the gases which are liqufied with diffculty. Gas deviates from ideal gas beheviour because moleculesA. are coloulessB. attract each otherC. contain covalent bondD. show Brownian Movement.

Consider the adjacent diagram. Initially, flask `A` contained oxygen gas at `27^(@)C` and `950 mm` of `Hg`, and flask `B` contained neon gas at `27^(@)C` and `900 mm`. Finally, two flask were joined by means of a narrow tube of negligible volume equipped with a stopcock and gases were allowed to mixup freely.
