http://orgchemboulder.com/Technique/Procedures/Distillation/Distillation.shtml WebThe boiling points increase down the group. The weak interatomic forces increase as the size and mass of the atoms increases. Density. The density of a substance is a measure of how heavy it is for its size. The particles in gases are spread far apart, so gases have low densities. Helium has the lowest density in the group.
