We used to think water followed this standard, existing as either a liquid, a solid (ice), or a gas (vapor), but H₂O might not be as simple as we previously thought.

The water is initially a solid at -40 °C, melts to become a liquid, and then evaporates to become a gas. Look through the slide show below to find out more about each stage of the heating curve ...

Researchers report that the way a tissue's cells are arranged can serve as a fingerprint for the tissue's 'phase' -- whether it is more like a solid, liquid, or gas. For example, tumors that are ...

Explain another change of state – liquid water to solid ice. Remind students that evaporation is a change in state from a liquid to a gas. Tell students that evaporation happens faster when water is ...

Water is unique. It is one of the only substances that can exist in nature as a solid, liquid and gas at the same time under ambient conditions (think of solid ice over a pond, which is liquid ...

It can be found inside gas giants such as Jupiter and is briefly created during meteorite impacts or in laser fusion ...

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 state, known as plasma .
