Outline


Introduction

  • the three types of heat transfer

The Three Types of Heat Transfer


Radiation

  • the transfer of heat from empty space
    • when you sit beside the fireplace you can feel the heat
    • the sun warms up the earth


Conduction

  • the heat transfer by direct contact
    • when you put a spoon in a boiling water
    • when you touch a hot pot


Convection

  • the heat transfer of heat using the movement of fluid
    • when you're boiling soup
    • the current of the mantle
