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.

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 ...

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 ...

You already know that water can have three states of matter: solid, liquid and gas. But scientists at the Oak Ridge National Lab (ORNL) have discovered that when it's put under extreme pressure in ...

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

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 ...

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 .
