Temperature is a way of measuring how fast the particles in
something are moving. 'Particles' are really little bits of stuff -
like atoms or molecules. If the particles are moving slowly enough,
they will even get stuck together and turn into a solid. And if they go
quickly enough, they will fly apart and become a gas. The faster the
particles are moving, the higher the temperature will be.
The Celsius system is based on the freezing and boiling points of
water. Water is a liquid, and like I was saying, if the particles slow
down enough, it will turn into ice (a solid). This is called freezing.
Every substance freezes at a different temperature (the 'freezing
point'), and the Celsius system was made up by saying that water
freezes at 0 degrees. But if you heat the water up, the particles will
be moving so fast that they can't stick together at all, turning the
water into steam (a gas). This temperature is called the 'boiling
point,' and for Celcius, they decided to make it so that the boiling
point of water is 100 degrees.
