Resembling glue or jelly; characterized by a jellylike appearance; gelatinous; as, colloid tumors., A substance (as albumin, gum, Gelatin, etc.) which is of a gelatinous rather than a crystalline nature, and which diffuses itself through animal membranes or vegetable parchment more slowly than crystalloids do; -- opposed to crystalloid., A gelatinous substance found in colloid degeneration and colloid cancer.

∙ 12y agoA type of solution of intermediate sized particles suspended and completely dispersed in another substance. Because the particles are not completely dissolved (although dispersed), it may or may not be a homogeneous mixture. Depending on the size of particles, the solution can be either; particles that are less than 10-9 m are homogeneous mixtures, particles that are 10-9- 10-6 m are colloids, and particles that are greater than 10-6 m are heterogeneous mixtures.
Colloids also exhibit the Tyndall effect, in which a beam of light is visible from the side, yet still passes through the solution. (You can see lasers through a mist or fog.)

∙ 12y agoA colloid is a mixture where one substance is completely dispersed in another one. For example milk can be simply described as a dispersion of cream in water. In colloids the solute is large enough to scatter light, but not small enough to be dissolved. You can see this scattering of light if you suspend flour in a glass of water it will look blue due to fine particles of flour scattering light.

A colloid is a state of matter in between solid and liquid. It's easy to imagine; a colloid is kinda like a mushy solid that will take the shape of it's container if it's forced. Some colloids include butter, glue, ice cream, tar, jelly, Jell-O, geletin, and jam.

What is mercurys aperance in room temp?
like gel...or colloide
Which boundary is a convergent boundary?
its when 2 tectonic plates converge or colloide
Which Criteria used to distinguish between true solution and colloids as no residue is left on filter paper on filtration?
In true solution the molecules of the solute get equally distributed throughout the solvent in the atomic level i.e. at the distance of diameter of an atom. While in colloides the molecules are not mixed in such state. So, using this as a principal to distinguish between colloide & solution. We can centrifuge the two mixtures to distinguish the colooide & solution.
Perform the activity to show tyndall effect?
take a cardboard box and draw 2 holes each on opposite sides.now take some water in a transparent jar and add sodium chloride to it now keep the solution in the box .now take a laser light,switch it on and through the hole throw the light inside .you will see that the light will not scatter.now take some water in another jar or half cut plastic bottle and add chalk powder to it.put the solution in the box and again throw light towards it .you will observe that the light scatters as water is a colloide
