Is Ranch Dressing a Liquid or a Solid? Imagine you’re sitting down for dinner. You pick up a bottle of ranch dressing, flip it upside down, and expect it to pour onto your plate. But nothing happens.

Substances can exist in three states of matter - solid, liquid and gas. Substances can change states. To change the state of a substance energy must be transferred to, or from, the substance.

Although the three states of matter are solid, liquid, and gas, not all substances seem to fit perfectly into one of these groups. Take a look at the substance below and see if you can decide whether ...

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 ...

In a gas, the particles ... changing from a solid to a liquid, for example. This basic model is, however, just that: there are many, many more states of matter out there that it doesn’t capture.

You probably learned in school that there are three states of matter: solid, liquid and gas. Think ice cube, a puddle of water and fog. Maybe you also learned about a fourth state, known as plasma .

Seems like a liquid. You probably learned in school that there are three states of matter: solid, liquid and gas. Think ice cube, a puddle of water and steam. Maybe you also learned about a fourth ...

Scientists have observed photons behaving as a supersolid, a unique quantum state where particles form a rigid structure but also flow without viscosi ...

You are likely well aware of the usual states of matter; solid, liquid, and gas, each coming with their own properties defined by the behavior of their component atoms. But there are others out ...
