1. Heat Transfer

2. Processes of Heat Transfer
There are three processes of heat transfer:
Radiation – Doesn’t need particles – wave energy
Conduction – Movement of heat in solids and liquids by movement of particles.
Convection – Movement of heat in solids, liquids and gasses by movement of particles.

3. Common Examples Radiation – heat from a fire; sunlight
Convection – boiling water; air currents
Conduction – frying pan; pots

4. Ways to Heat our Homes

5. Firewood
Oil
Electricity
Hot water Radiation
Geothermal
Heat Pumps
Solar

6. Types of Insulating Technologies

7. Animal fur
Refrigerator
Thermos
Fiberglass insulation
Sod
newspaper

8. Insulators vs. Conductors
Insulators are materials that slow down heat loss. Eg. Your winter coat
Conductors allow heat to move easily. Eg. A Frying pan.

10. Specific Heat Capacity
The amount of heat energy that a substance can hold is called specific heat capacity. Substances with large heat capacities will take longer to warm up and cool down. The unit is J/g oC.

11. Specific Heat Capacities

Design A method to keep snow and ice off your drive way. Draw a sketch or make a model of what it would look like.

13. Careers in Heat
There are many jobs that a person might have that involve heat and temperature.
Furnace repair person
Light bulb manufacturer
Blacksmith
Volcanologist
Glass blower

14. Business Card
Using a computer, create a business card for a person with a career associated with heat and temperature. Include responsibilities required for the job.
