Learn all about the states of matter - solid, liquid and gas. We explain the concepts of freezing, melting, evaporation, and condensation, and discuss the reversibility of physical changes. We also distinguish between physical and...

What's the difference between a physical change and a chemical change? What are elements, compounds, pure substances, and mixtures? So many definitions to learn! Don't worry, Professor Dave will take you through the details.

The video explains the three main states of matter, which are solids, liquids and gases, and their properties. The concept of state symbols is introduced to indicate what state chemicals or particles are in a reaction. The video also...

Composite functions In the introduction to functions video, we discovered what functions are, what domain and range mean and how to solve some problems. We saw that they could be called f(x) or g(x) or any letter. In this video, we’re...
