Substances can exist in three states of matter - solid, liquid and gas. All substances are made from particles, and the forces between the particles are different in solids, liquids and gases. The ...

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 more ...

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 ...

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 stuff ...

In school, students are taught that matter is either solid, liquid, or gas. Now, physicists discover that atoms can actually exist as solid and liquid simultaneously. It turns out, when certain ...

The theory of non-ideal gases at thermodynamic equilibrium, for instance the van der Waals gas model, has played a central role in our understanding of coexisting phases, as well as the transitions ...

The change in temperature of a body causes expansion or contraction of that body. Most of the substances expand on heating and contract on cooling. This is called thermal expansion. It has been ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. How many states of matter are there? When you were young, you probably ...

Finally, they watched the whole process using static solid-state deuterium nuclear magnetic resonance (NMR) spectroscopy.

Save guides, add subjects and pick up where you left off with your BBC account. The units of density depend on the units used for mass and volume. The most commonly used units are grams per cubic ...
