Countless Earnhardt fans honor The Intimidator by remaining fans of Dale Jr. It's a family tradition. And although Dale Jr. has not enjoyed the success of his father, few drivers enjoy his popularity. Earnhardt Jr. has, in fact, been voted NASCAR's most popular driver each of the last eight years.
A colloid is a mixture of a small insoluble particles that are dispersed in a medium and do not settle out (in any practical period of time). colloid is a type of mechanical mixturewhere one substance is dispersed evenly throughout another.
Colloids are either colored or translucent due to light reflecting on the particles within them. Some examples of colloids include pumice, gelatin, smoke, dust and milk of magnesia. The term colloidal suspension is referring to a substance that has a solid permanently suspended in a liquid. In order to determine if a substance is a colloid or merely a solution you can check for Brownian movement, the constant motion of particles in solutions and colloids. This movement and its constancy are true of both substances yet if the substance is a colloid the particles will resist settling to the bottom.
