The state of matter is a deceptively simple concept. It turns out that any material, no matter what it is made of, can exist in one of three forms: solid, liquid or gas. These are categories of ...

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 ...

Researchers at Duke University have uncovered the molecular inner workings of a material that could underpin next-generation rechargeable batteries.

Solid-state cells promise faster recharging, better safety, and higher energy density. They replace the liquid electrolyte in today’s lithium-ion cells with a solid separator. Honda, Toyota ...

The particles of a solid are very close together. It melts when it changes from the solid state to the liquid state. The same mass of liquid will have slightly greater volume than the solid.

Condensed-matter physics is the study of substances in their solid state. This includes the investigation of both crystalline solids in which the atoms are positioned on a repeating three ...

Solid-state clock Illustration of how thorium atoms are vaporized (bottom) and then deposited in a thin film on the substrate ...

It does not matter if a substance melts ... For example, ice is water in the solid state: ice melts to form water in the liquid state when it is heated water in the liquid state becomes ice ...

Water is the only substance on Earth that occurs naturally as a solid, liquid ... substances and watch them morph into different states of matter. Along the way, you'll see just how inextricably ...
