Question

hey guys ☺☺ define the terms:

(1) coagulation ☺

(2) emulsions ☺ with examples

Good answer will get the brainliest.☺☺

Good luck ☺☺☺☺

Answer 1

Ciagulation= the action or process of a liquid, especially blood, changing to a solid or semi-solid state.


Emulsion=. An emulsion is a colloid of two or more immiscible liquids where one liquid contains a dispersion of the other liquids. 
Oil and water mixtures are emulsions when shaken together. ...

Egg yolk is an emulsion containing the emulsifying agent lecithin.

Crema on espresso is an emulsion consisting of water and coffee oil.

Answer 2

1. COAGULATION -

The process of changing from a liquid to a gel or solid state by a series of chemical reactions, especially the process that results in the formation of a blood clot.

verb (used with or without object),co·ag·u·lat·ed, co·ag·u·lat·ing.

process of changing from a liquid to a gel or solid state by a series of chemical reactions, especially the process that results in the formation of a blood clot.

Biology . (of blood) to form a clot.

Physical Chemistry . (of colloidal particles)to flocculate or cause to flocculate byadding an electrolyte to an electrostaticcolloid.

adjective Obsolete - coagulated


Synonyms for coagulate


1. clot, set, solidify, thicken.

Coagulation (also known as clotting) is the process by which blood changes from a liquid to a gel, forming a blood clot. It potentially results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair. The mechanism of coagulation involves activation, adhesion, and aggregation of platelets along with deposition and maturation of fibrin. Disorders of coagulation are disease states which can result in bleeding (hemorrhage or bruising) or obstructive clotting (thrombosis).[1]

Example of coagulation -

Coagulation is the process of particles clumping together when their oppositely charged particles aggregate together and then gravity causes them to settle on the bottom. Just like opposite charges on a magnet will pull together, the opposite charges on the particles in the colloid will pull together, until aggregates that are too large to be held in suspension are formed. These then fall out of the colloid due to gravity.

Other EXAMPLE of coagulation that you're probably already familiar with include blood clotting to stop a cut from bleeding and gravy thickening as it cools.


2. EMULSIONS -

An emulsion is a mixture of two or more liquids that are normally immiscible(unmixable or unblendable). Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably, emulsion should be used when both phases, dispersed and continuous, are liquids. In an emulsion, one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include vinaigrettes, homogenized milk, mayonnaise, and some cutting fluids for metal working. Graphene and its modified forms are also a good example of recent unconventional surfactants helping in stabilizing emulsion systems.[3]

The word "emulsion" comes from the Latin mulgeo, mulgere "to milk",[specify] as milk is an emulsion of fat and water, along with other components.



What is an Emulsion?

Emulsions are biphasic liquid systems consisting of two immiscible liquid phases. These phases are present in such as way that one phase is dispersed in the other continuous phase. Emulsions are part of a more general class of two-phase systems of matter called colloids.

Although the terms colloid and emulsion are sometimes used interchangeably, the term emulsion is used only when both the phases are in a liquid state. Examples of emulsions include mayonnaise, milk, lotions, etc.
Properties of Emulsions

Emulsion particles unavoidably form dynamic inhomogeneous structures on small length scale.Emulsions are highly unstable systems and require an emulsifying agent or emulsifier ( These are usually surface active agents also known as “surfactants”)Emulsions are prepared by continuous mixing or agitation of the two phasesWhen kept for longer periods of time or in case of absence of an emulsifying agent, the phases in the emulsion tend to separate, resulting in “cracking of emulsion” or ” phase inversion”.
