Hi there! I'm Sofia and welcome to your lesson on particle theory.
Today we're going over Conduction, Convention and Radiation.
These 3 words are ways that move heat from one place to another.
Conduction is heat going through solid things such as a wall.
Convection is heat going through fluids like water and gases like air.
Radiation is heat going through anything it can. For example it can go through metal or a vaccuum.
All of this happens because of particle theory, which is made up out of, solid particles, liquid particles and gas particles. The solid particles stick close together and vibrate. The liquid particles are farther apart and move around. The gas particles stay far away from each other and move around freely.
All the heat comes from how fast the particles move. Like when you rub your hands together fast they get hotter. When the particles move together the heat is created and the hot energy spreads and passes through other things.
