An emulsion is a type of colloid, but a colloid is not necessarily an emulsion. Other types of colloids include foams and gels.
An emulsion is where the dispersed phase and the continuous medium are both liquids. Typically the liquids are immiscible. An examples of emulsions are vinaigrette, (vegetable oil and vinegar)
A colloid is a more general term for a dispersed phase and continuous phase system, examples are fog liquid/gas colloid; pumice; gas solid foam. An emulsion is a special case of this.
They are about the same, emulsions are part of (the more general) colloidal sytems.
Colloids are a solution of (at least) 2 phases, 1 continuous and 1 dispersed. The dispersed phase is small particles of between 1 and 1000 nm meaning that they sufficiently and equally mix amongst the continuous phase without separating due to gravity. e.g. smoke, fog, glue etc.
Emulsions are again at least a 2 phase mixture and are generally liquids but the dispersed phase is a grouping of flocculated particles that require to be held together (and separate from the continuous phase) by a surfactant or "emulsifying agent" which decreases the interfacial tension. e.g. milk (milk fat in water with proteins acting as the surfactant), mayonnaise (fat in water with egg yolk lecithin as the surfactant). Without the surfactant the emulsion is unstable and will separate into two phases as a result of gravity, e.g. vinaigrette (vinegar and vegetable oil with no emulsifier)

Kool-aid is a good example of homogeneous mixture. In any homogeneous mixture, all the species making up the solution are in a defined ratio. There are other two types of solutions that yields a heterogeneous mixture, namely, colloids and emulsions.
Emulsions will settle into layers when they are left standing undisturbed.
Colloids are stuck between heterogeneous and homogeneous mixture. So you can't say that it is a heterogeneous or homogeneous. It is both.
No, for jellies, dispersion phase is liquid and dispersion medium is solid. And for emulsions,both dispersion phase and dispersion medium is liquid.
These colloids are called emulsions.

A colloid is a homogeneous, noncrystalline substance consisting of particles of one substance dispersed through another substance. Some common colloids are gels, sols, and emulsions. Particles cannot be separated out by ordinary filtering or centrifuging and will not settle.
A colloid is a mixture where the interspersed particles are of such size that the mixture will not settle out on its own. Examples include things like gels or emulsions.

Answer:D I had the same question but I figured it out. It is C. Colloids.
After my opinion they are not colloids.
Suspensions and colloids exhibit the Tyndall Effect. When a beam of light is shone on either of these mixtures, it will be scattered by the continuous movement of the particles and not shine through to the other side.

X Ray film emulsions are sensitive to light.
salad is a heterogenious mixture and a coloid is a type of heterogenious mixture but they're not the same. i suppose it depends on if you have dressing or not, b/c it could start separating( the sauce would go down).
