| Résumé : |
There are four states of matter : solid, liquid, gas and plasma. Many readers will be surprised to see plasma, as it is a recent addition to what is taught in schools. To get to liquid, melting a solid requires energy (normally heat). Likewise, the same is needed to go from liquid to gas and then to plasma.
Liquid to gas transitions is called vaporisation, and gas to plasma transitions are called ionisations. Staring into the flame of a campfire means you are looking at the state of matter called plasma — the colour depends on the heat, with a higher energy plasma being white and giving off all the frequencies of visible light. |
