How is matter different from mass? These and other questions about the deepest levels of physics, answered inside.

It turns out that any material, no matter what it is made of, can exist in one of three forms: solid, liquid or gas. These are categories of stuff that have certain observable properties.

Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

Fluid statics, dynamics of fluids, properties of solids, advanced topics in waves and vibrations, temperature and heat flow, kinetic theory of gases, thermodynamics, and the limits of classical ...

The three states of matter can be represented by the particle model. This model explains the properties of substances in their different states, as well as changes of state. Interactive activity ...

Based on the interlocking structure of chainmail, this material has all the best parts of both solids and liquids.

The field of condensed matter physics explores the macroscopic and microscopic properties of matter. Condensed Matter physicists study how matter arises from a large number of interacting atoms and ...

"This work opens a promising new avenue for investigating the self-interacting properties of dark matter through stellar streams," team leader and University of California, Riverside researcher ...
