How Snow Is Made
The phrase “no two snowflakes are alike” is actually scientifically accurate. Snow forms high in the atmosphere, and despite its uniform appearance, each snowflake is different based upon where and how it was formed. Although snowflakes...

Intermolecular Forces and Boiling Points
Why do different liquids boil at different temperatures? It has to do with how strongly the molecules interact with each other. Find out all the different ways, and how to use them to make predictions about matter!

Covalent Bond Energy and Length
We've already learned about different types of chemical bonds, including covalent bonds. But now that we know about enthalpy, and orbitals, and some other concepts, let's revisit the covalent bond and dig a little deeper.
