Conduction is the transfer of energy that occurs when molecules bump into one another. In other words, the heat is transfered through touch.
Alice and Ms. Bird walk outside. Ms. Bird is crouched down low on the scorching hot sidewalk, she quickly explains to Alice that the atoms in the particle heat up. Since this is making the sidewalk hot, Ms. Bird's knees are warming up too. The sidewalk is acting like an insulator, it is containing all the heat.
What about convection, how does that work?
Convection is when heat waves travel throughout the atmosphere giving off steam. For example, the sun transfers heat down to this lake. Then the heat travels up, causing it to create steam.
Radiation is the energy that travels in waves or rays. Take a look at this lake, we see the sun beating down on the lake. This causes the temperature of the lake to increase, this also means the kinetic energy is moving very fast.
Ms. Bird, what does radiation mean then?
I don't think so, let's just go back to school , Ms. Bird.
Do you have any other questions about heat transfer Alice?
You've had a long day, I think you deserve to go home.
