LO: Considering the water cycle in terms of changes of state of water
As you have already learnt, substances can exist in different states: Solid, liquid and gas. Water is no exception.
All substances have these different points where they change states. Iron becomes a liquid (melting point) at 1535 °C and turns to a vapour (boiling point) at 2750 °C!
Scientists have always been looking at the stars in search for new planets and life, far beyond our own solar system. In 2017 scientist discovered a planet which is hot enough to turn metal into gas! The planet is called KELT-9b and it’s a gas giant with the designation of “ultra-hot Jupiter”. It’s located 650 light years from Earth and it’s atmospheric temperature is over 4000°C! That’s enough to turn iron and titanium into vapour!!
If you live in a snowy super cold place you can take a pot of boiling water and change it’s state instantly! Check out the video below. This has to do with water’s ability to change states.
