Teacher can you teach me about the particle theory
The first thing you need to know is that there is a theory called the particle theory and it basically explains why there are different states of matter which are solid liquid and gas.
wow thats cool
All matter is made up of small particles
All particles in a pure substance for example water are the same. Different substances such as milkshakes are made up of different particles.
I didn't know that
There is space between particles the amount of space depends on the state of matter. the particles for a solid are tightly packed together with very little space in between them, while a liquids particles are more spread out and gases are very spread out
Particles are always moving the more energy they gain the faster the particles move and in some cases the matter can change state for example if you boil water it turns to a gas
