Jonny Nelson explains how changes in a material’s temperature or state of matter are caused by changes to internal energy. The energy required by different materials depends on their heat ...

SUNAYANA: And looking at what’s going on according to the particle model. And we’ll be looking at how adding or taking energy away from a substance can convert it from one physical state to ...

The sun, a searing hot sphere of gas primarily composed of hydrogen and helium, boasts surface and outer atmospheric ...

The Standard Model is a kind of periodic table of the elements for particle physics. But instead of listing the chemical elements, it lists the fundamental particles that make up the atoms that make ...

Using the Large Hadron Collider (LHC), a team of researchers recently tested whether top quarks also follow the special ...

Students will be able to develop and explain a particle-level model to describe their observations of water dissolving salt, the water evaporating, and the salt crystals re-forming. Dissolving a solid ...

The sun’s solar wind, made of charged particles, interacts with powerful eruptions, affecting cosmic rays and space weather.
