is blood an emulsion? are milk and milk in water both colloids? pls ans in context to class 9 ncert is matter around us pure?
Answers
Step-by-step explanation:
An example of a colloid is milk. Milk is a mixture of liquid butterfat globules dispersed and suspended in water. Colloids are generally considered heterogeneous mixtures, but have some qualities of homogeneous mixtures as well. Smoke is a mixture of particles that are suspended in the air.
An emulsion is a mixture of two or more liquids that are normally immiscible (unmixable or unblendable) owing to liquid-liquid phase separation. 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, liquid biomolecular condensates, and some cutting fluids for metal working.
