Write the definition solution, suspension,colloids compounds, physical change, chemical change, elements?

Answer 1

Answer:

Suspension in science refers to a mixture where a solid particle does not dissolve in a liquid solution. ... Emulsions are a type of suspension, where two immiscible liquids are mixed together. Examples of suspended solutions include salt water, sand in water, and muddy waterCommon examples of suspension include the mixture of chalk and water, muddy water, the mixture of flour and water, a mixture of dust particles and air, fog, milk of magnesia, etc.

Types of physical changes include boiling, clouding, dissolution, freezing, freeze-drying, frost, liquefaction, melting, smoke and vaporization.

Liquefaction Changes.

Sand in water is an example of a suspension. A solution is a homogenous mixture of two or more substances where one substance has dissolved the other. An example of a solution is saltwater . Colloids are homogenous mixtures where the particles are small enough that they stay suspended.

Mixtures can be classified into three types: suspension mixture, colloidal mixture or solution, according to how they combine and can be separated. Suspension mixtures have larger solute particles, colloidal mixtures have much smaller particles, and particles in a solutions completely dissolve into the solvent.

Colloids are common in everyday life. Some examples include whipped cream, mayonnaise, milk, butter, gelatin, jelly, muddy water, plaster, colored glass, and paper. Every colloid consists of two parts: colloidal particles and the dispersing medium.

Answer 2

$\huge\mathcal{Solution}$

a way of solving a problem, dealing with a difficult situation, etc.

$\huge\mathcal{Suspension}$

not being allowed to do your job or go to school for a period of time, usually as a punishment.

$\huge\mathcal{Colloid}$

a homogeneous non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance. Colloids include gels, sols, and emulsions; the particles do not settle, and cannot be separated out by ordinary filtering or centrifuging like those in a suspension.

$\huge\mathcal{physical change}$

Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.

$\huge\mathcal{Chemical change}$

Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis.
