Hello, little scientists, I am Professor Bill Tyson and together we are going to know different forms of science. Have you ever seen about the states of matter, but did you know that each of the changes has a name? That's what we'll see.
When we have a solid state substance and it is heated, the molecules start to move away and it goes into the liquid state. This process we call Fusion. In the reverse process, if we have a liquid substance and it is cooled, its molecules stay at rest and approach until it reaches a solid state.
This process is called Solidification. But there are other transformations. When a liquid substance is heated, its molecules get even more agitated and further apart, and it goes into the gaseous state.
This process is called Vaporization. When the process is contrary, we cool a gas. Their molecules are at rest, so close together and the substance becomes a liquid.
The name of this process is Condensation. And there is a last process, which is when a solid-state substance is heated very quickly, the molecules leave the home directly to a frenetic state, and the solid passes directly into the gaseous state. This process is called Sublimation.
The reverse process, when a gas cools quickly to a solid, also bears the name of Sublimation. And these are the processes that form the physical states of matter. Now I'm going to make my tea because the water I put to warm up is already evaporating.
For now, it's just personal, see you next time. Just one more thing. If you, like me, believe in the importance of teaching science to children, share this video.
