In physics, it is known that the surface tension of a liquid, caused by intermolecular cohesive forces, tends to minimize the ...

Ethanol (CH 3 CH 2 OH) is a liquid at room temperature (boiling ... the molecule itself is non-polar and the only intermolecular force present will be weak London dispersion forces.

They leave the column as a hot liquid called bitumen. Shorter hydrocarbon molecules have weaker intermolecular forces and lower boiling points. They are highly volatile and therefore extremely ...
