Dew forms in the morning on leaves and grass because the warmer air deposits water molecules on the cool leaves. The faster they move the more energy they contain. When energy is applied to a liquid, the particles that make up a liquid begin to move about so rapidly, that they can no longer hold themselves together. A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance.

Here are several examples of independent and dependent variables in experiments: In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score. Examples of Colloids- Colloids refer to dispersions of small particles usually with linear dimensions from around 1 nm to 10 micrometers. Due to the movement of the molecules inside the fluid, internal friction occurs, and how the fluid interacts with other matter, external conflict occurs. The properties we look at are shape, mass, and volume. Liquids are considered the second state, between solids and gases. In order for two liquids to be the same substances, they must have the same properties. The volume, however, does not change, because the particles are still part of one another.
