Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An unknown liquid is provided in a science class. After observing the liquid for a while, a student notices that particles in the liquid separate out over time. What type of matter best classifies this liquid?
A
colloid
B
compound
C
suspension
D
solution
Explanation: 

Detailed explanation-1: -If a liquid is suspended in another liquid, it is called an emulsion.

Detailed explanation-2: -The particles in a colloid are large enough to scatter light, a phenomenon called the Tyndall effect. This can make colloidal mixtures appear cloudy or opaque, such as the searchlight beams shown in Figure 2. Clouds are colloidal mixtures.

Detailed explanation-3: -A solution is a mixture where one of the substances dissolves in the other. The substance that dissolves is called the solute. The substance that does not dissolve is called the solvent. An example of a solution is salt water.

Detailed explanation-4: -Filters can separate particles that make up a suspension. Suspended particles settle out of a suspension. Colloids contain some particles that are intermediate between those in a solution and those in a suspension. Examples include peanut butter, pudding, Jello, whipped cream, and even fog!
