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.

The transport of dense gases and liquids is becoming increasingly relevant in relation to carbon capture. Research published in The Journal of Chemical Physics is helping us understand more about how ...

After viewing a model of salt, students help develop models for the processes of salt dissolving, water evaporating to form a gas, and salt re-forming as a crystal. The focus is that matter, whether ...

Ranch dressing is actually a fifth state of matter known as soft matter. Soft matter can have properties of both liquids and solids, so materials scientists say it is viscoelastic – a combination of ...

Observation of a glass of water reveals that the water exists in two distinct phases: liquid and gas. Even at room temperature, water molecules are constantly evaporating from the surface of the ...

Scientists have uncovered a key finding to one of water's unique properties: at high pressure and low temperature, liquid water separates into two distinct liquid phases -- one high-density and one ...

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.
