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 ...

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 ...

Ellingham diagrams are very powerful phase diagrams to evaluate equilibrium phases under gas-solid reactions. Those phase diagrams were extended to higher pressures to examine stable phases under high ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 221, No. 1144 (Jan. 7, 1954), pp. 1-28 (28 pages) This paper considers the flow of a gas through a porous ...

Everything in the universe is made up of matter, small non-visible particles called molecules and atoms. At school, we were taught that there are three states of matter; solid, liquid and gas.

Almost everything is made of particles. Particles can be atoms, molecules or ions. Particles behave differently in solids, liquids and gases. The particle model explains the differences between solids ...

Students are introduced to the idea that matter is composed of atoms and molecules that are attracted to each other and in constant motion. Students explore the attractions and motion of atoms and ...
