States Of Matter
Solids like to hold their shape. In the same way that a large solid holds its shape, the atoms inside of a solid are not allowed to move around too much. Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want. Details, Shape memory metals can remember their shape,Some solids can be hammered or squashed into many different shapes without breaking. Some solids, such as the metal copper, can be pulled and stretched easily into extremely thin wires.
Liquids are the second state of matter we will talk about. Solids are objects you can hold and maintain their shape. Gases are floating around you or trapped in bubbles. Liquids are found between the solid and gas states. Facts: Mercury is a liquid metal that is poisonous, A measure of how fast or slowly a liquid can flow is its viscosity, their volume always stays the same.
- A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture would contain a variety of pure gases much like the air. Fact: Gas pressure is measured in pascals. Pure gases are made up of just one atom. Neon is an example of a pure gas. Like solids and liquids, gas is a common state of matter.
A Bose–Einstein condensate (BEC) is a state of matter of a dilute gas of bosons cooled to temperatures very close to absolute zero (that is, very near 5000000000000000000♠0 K or 5000000000000000000♠−273.15 °C) Fact: Although it had been predicted for decades, the first atomic BEC was made only in 1995, The Bose-Einstein state of matter was the only one created while your parents were alive.
