What is a heterogeneous mixture

Heterogeneous means of different types. So a heterogeneous mixture is a mixture of dissimilar items. Homogeneous means of the same type so a homogeneous mixture would be a mixture of similar items.

A mixture where two or more substances are mixed together but are not chemically combined is called as an heterogeneous mixture.

In chemistry, heterogeneous mixture is a mixture of two or more different substances in the form of solution or colloids. For example, salad is an heterogeneous mixture


A heterogenous mixture is not uniform in composition and properties throughout.
What term describes the physical change of a solid to a liquid at the melting point

melting

How would the kinetic theory address

Vibrations in molecules

What factors are included on a phase diagram
