Why do bigger molecules have higher boiling points? First there is molecular size. Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules. … The attractive forces between the latter group are generally greater.
Do more massive molecules have higher boiling points? In general, larger molecules have higher boiling points than smaller molecules of the same kind, indicating that dispersion forces increase with mass, number of electrons, number of atoms or some combination thereof.
Why do large polar molecules have higher melting and boiling points? Polar molecules have strong intermolecular forces of attraction. It takes more energy to separate the molecules from each other, so polar substances have relatively high melting points and boiling points.
Why do you boil tofu? It may seem counterintuitive to add water to something you’re trying to dry out, but boiling water will actually cause the tofu to squeeze out more moisture, bringing it to the surface and making it easier to blot off, while the salt gently seasons the slices.

Does tripe smell when it’s boiling?
While you can use tripe to cook mouth-watering dishes, its foul smell when not yet prepared or cleaned might be a huge turn-off to home cooks and foodies. It is described to smell rotten, fishy, or just plain pungent.
Can i use boiled linseed oil on leather?
Boiled linseed oil, a variation, is often combined with other chemicals that can be harsh to the leather. In the short term it can help add and retain moisture, though in the long term it can lead to faster wearing and cracking of the leather fibers. A leather-specific oil, such as Lexol, would work much better.

What makes a solute better at raising the boiling point?
A solvent’s vapor pressure will lower when a solute is added. This happens because of the displacement of solvent molecules by the solute. … For the vapor pressure to equal the atmospheric pressure, a higher temperature is required, and a higher boiling point is observed.
What causes boiled eggs to stick to the shell?
The best eggs for boiling are at least a week to ten days old. If an egg is fresh, the pH of the white is super low, which causes it to stick to the shell membrane.
