Students are introduced to the idea that matter is composed of atoms and molecules that are attracted to each other and in constant motion. Students explore the attractions and motion of atoms and ...

However, the liquid is quickly heated and starts to expand. It expands more than the solid glass and so the water level rises back to A and then up to, and beyond, C. Molecules within gases are ...

The atoms of a solid are strongly attracted to each other. Solids keep their shape because of these strong attractions. The atoms vibrate but do not move past each other.

Earlier this week we broke down the complexities of mixed-phase precipitation forecasting.Within that we briefly touched on a key component to that complexity w ...

Structure of solids and liquids is the study of the physical properties of matter in which there is a non-negligible interaction between the constituent atoms or molecules. While the atoms or ...

One area of investigation has been the impact of alkylthio groups on the phase transition behavior of liquid crystal molecules ... such as from solid to liquid or liquid to gas.
