What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...

Miscibility
The ability of one liquid to mix with (dissolve in) another liquid.
Vapor Pressure
The particle pressure of a vapor at the surface of its parent liquid.
Neutralization
The reaction of an acid with a base to form a salt and water. Usually, the reaction of hydrogen ions with hydrogen ions to form water molecules.
Covalent Bond
Chemical bond formed by the sharing of one or more electron pairs between two atoms.
Supercooled Liquids
Liquids that, when cooled, apparently solidify but actually continue to flow very slowly under the influence of gravity e.g glass.
Daughter Nuclide
Nuclide that is produced in a nuclear decay.
Specific Gravity
The ratio of the density of a substance to the density of water.
Nuclear Binding Energy
Energy equivalent of the mass deficiency, energy released in the formation of an atom from the subatomic particles.
Alpha (a) Particle
Helium ion with 2+ charge, an assembly of two protons and two neutrons.
