2. The energy transferred from a hotter object to a colder object. – The hotter something is, the faster its molecules are moving. – Does ice have heat? Heat

3. Three ways it is transferred: – Conduction – Radiation – Convection Heat Transfer

4. Heat transfer by direct contact of particles of matter Particles bump into each other and transfer their energy heating them up. Conduction

5. The transfer of energy through empty space Moves in waves – Sunlight – Open fire. Climate Radiation

6. Safety

7. Heat transfer by the circular movement of particles (liquids and gasses) Particles transfer heat Caused by differences in density. Convection

8. Density = Mass / Volume Heated Fluids: – Move faster and bump into other particles – They spread out increasing the volume – Density decreases. How Convection Works

9. Cooling Fluids – Move slower – They come together, decreasing the volume – Density increases. How Convection Works
