Why do branched molecules have lower boiling point? Branched alkanes normally exhibit lower boiling points than unbranched alkanes of the same carbon content. This occurs because of the greater van der Waals forces that exist between molecules of the unbranched alkanes. These forces can be dipole‐dipole, dipole‐induced dipole, or induced dipole‐induced dipole in nature.
How is boiling point affected by branching? Weaker intermolecular forces means that less energy is required to separate the molecules of a compound from its liquid surface, thus lowering the boiling point. As branching increases, the surface area decreases and hence the intermolecular forces of attraction which ultimately results in decrease of boiling point.
How long do I boil frozen wontons? Don’t overcook your wontons. Wontons easily tear when they overcook.

How to reduce silica in boiler water?
Lime softening is one of the most common methods for removing silica from water such as make up to cooling towers, make up to boilers or boiler blow down water. Lime softening utilizes the addition of lime (calcium hydroxide) to remove hardness (calcium carbonate and magnesium carbonate) ions by precipitation.
