Did you know that it's possible to walk on water? In order to do this, it's important, however, to use contained or ''solid'' water and not ''liquid'' water. When it comes to liquids and solids, the tendency for the molecules to flow relates to what's holding them together....
Why can't solids be compressed? Why are transition metal compounds colored? Why is ice the solid form of water? How does temperature affect chemical changes? Why do liquids evaporate at different rates? Why is density important as a property of matter?
Why amorphous solids are called as supercooled liquids? 01:34 Why benzoic acid has a sharp melting point but glass does not? 02:08 Classifiy the following into inoic, molecular, covalent and metallic c... 02:27 A CsCl crystal is found to have NaCl structure. How it happened? 01:14 ...

Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different substances, including solids, liquids, and gases that are all around us. Models can be used to represent atoms and these models can be rearranged to repres...

As the name "hydrogen bond" implies, one part of the bond involves ahydrogenatom. The hydrogen must be attached to a strongly electronegative heteroatom, such asoxygen,nitrogenorfluorine, which is called the hydrogen-bonddonor. This electronegative element attracts the electron cloud from around the...
4. Behavior of Liquids: - Liquids have particles that are also close together, but they have slightly more space between them compared to solids. - While liquids can be compressed to a very small extent, the compressibility is much lower than that of gases. The intermolecular forces in li...
In a different context I’ve discussed the concept of a “mechanoidal phase”, distinguished, say, from solids and liquids by the presence of a “bulk orchestration” of underlying components. It’s something closely related to class 4 behavior. And it’s int...
Vapors: Created when liquids evaporate (changing from a liquid state to a gaseous state) or solids sublimate (changing from a solid state to a gaseous state, bypassing the liquid state all together). Cartridge Care A respirator cartridge starts working from the moment you open the package it ...
