Why do compounds with strong intermolecular attractive forces have a higher boiling points than compounds with the weak intermolecular attractive forces? provide an answer using 3-4 sentences.

Higher the inter-molecular attractive force of a compound, higher the energy required to break those bonds. Therefore, their boiling points are higher.

Explanation:

The molecules of liquid are free to move in their lattice. But they cannot, leave their lattice or layer, because of the inter-molecular attractive forces. These forces form a bond among molecules. The boiling point is that temperature at which the molecules of liquid acquire enough energy that they overcome these inter-molecular attractive forces and leave the layers of liquid breaking the bonds. Hence, they are converted to gases. This is the reason that compounds with strong inter-molecular forces require more energy to break bond and hence, their boiling points are higher than compounds with weak inter-molecular attractive forces.

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

it's filtration, but this is an assumption so my apologies if i got this
