Chemically, substances are classified into three types, solids, liquids and gases, but if it is said to classify a swinging fire as one of these three, you should be troubled by the answer. What on ...

Solids, liquids and gases. In a solid like this brick, the particles are regularly arranged touching their neighbours and move only by vibrating. This explains why solids have a fixed shape. In a ...

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 ...

Everything around you - and even your body - is made up of the three phases of matter. Let's find out more. The whole world and everything we can see around us is made up of matter. Matter can be ...

THE tenets of physics can seem carved in stone. The speed of light is a constant. There are four fundamental forces. Theoretically, rules like these are open to revision. But new contenders had better ...

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 ...

The liquid-gas interface trapped on underwater solid structures has multiple excellent properties, such as drag reduction, anti-biofouling, and anti-corrosion, and that is why it has a promising ...

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 ...
