Conduction This is the way heat transfers through . When the particles near the heat source heat up, they get

more and start to more. They with the other particles and

pass energy to them. Then these paticles start to move more and with the other particles. This

process continues until all the particles have the same energy and the whole objecvt is the same .

Convection

This is the way heat transfers through and . The particles are near the heat source

heat up and start to move more. They more from the other particles, so this part becomes less

. Because it is less dense, it . Cold particles move to fill the

that is created. Then they heat up and , cool down and , heat up and

cool down and . This is calleda convection.

Radiation

This is how heat trasnfers without physical . It is how the ’s energy

reaches us on Earth or how we feel the heat of a without touching it for example
