Why is it that solids have very high boiling points and melting points?
Well,its because the particles that constitute solids are closer together hence the forces of attraction are greater rising the boiling point and melting points are raised as the heat try to break the bonds
Apply Concepts and enspIn general when would you use filtration to separate a mixture When would you use distillation to separate a mixture?
- Filtration is a method of separation when we want to separate solids from a liquid.- Distillation is a method of separation when we want to separate the components of a liquid mixture, relying on the differences between boiling points.
Why are boiling points of liquids usually reported along with the pressure at which the boiling point was measured?
The boiling point of a liquid is influenced by pressure: lower pressure leads to lower boiling point. Therefore, reporting the pressure at which the boiling point was measured gives context to the boiling point value and ensures consistency in comparison among different samples.
Are the trends for melting point and boiling point the same as nonmetals and explain?
No, the trends for melting points and boiling points in nonmetals are generally different from those in metals. Nonmetals typically have lower melting and boiling points compared to metals, which tend to have high melting and boiling points due to strong metallic bonds. In nonmetals, the melting and boiling points can vary significantly based on molecular structure and intermolecular forces, with noble gases having very low points and some covalent network solids like diamond having high points. Therefore, while both groups exhibit trends, the underlying reasons and values differ significantly.
What type of solids are generally boiling?
Metals have a boiling point.
How do you identify solids at melting or boiling points?
Melting and boiling points are different for each compound or element.
Define amorphous solid?
Generally they are two types of solids 1. Crystalline solids 2. Amorphous solids. Amorphous solids are those solids which having different properties in different directions. They didnt have sharp melting and boiling points.
What could be separated by distillation or filtration?
Substances that have different boiling points can be separated by distillation, as the liquid with the lower boiling point will vaporize first. Filtration is used to separate solids from liquids, where the liquid passes through the filter while the solid particles are retained.
What can be used to separate parts of a mixture?
If the mixture is a mixture of solids and if one of constituent is a ferromagnetic substance, a magnet can be used to separate the magnetic and non-magnetic substances. If one of the constituent is a sublimate, sublimation can be used. If the mixture is a mixture of solids and liquids, decantation, filtration and distillation can be used. If the mixture is a mixture of liquids, fractional distillation can be used to separate the different constituents taking advantage of the difference in boiling points of the different constituents.
Is there a boiling point for a solid?
All elements have boiling points. All element can also become solids if cooled to the proper temperature. However, with the vast number of solids in the world, there are just as many boiling points.

The boiling points of ionic solids tend to be?
The boiling points of ionic solids tend to be very high.

Ways to separate mixture?
Some common methods to separate a mixture include filtration, distillation, chromatography, and evaporation. Filtration is used to separate solids from liquids, while distillation can separate liquids based on their boiling points. Chromatography is effective for separating different components in a mixture based on their interactions with a stationary phase, and evaporation can be used to separate a solvent from a solute.
Separating solids and mixtures?
Methods of separation are: decantation, filtration, sieving, electromagnetic, centrifugation, distillation, ion exchange, gravitational system, elutriation, radiometric sorting, zone refining, sublimation and many others.
