Unit c heat & temperature notes(heating tech)

1. Heating Technology

2. Heating Technology
Furnaces and Air conditioners are examples
of technologies we use.

3. Heating Technology Timeline
7000 BC or earlier:
Humans Created Fire
100 BC: Romans
developed central heating
(heat travels from 1
source to different areas
in a building)

4. Heating Technology Timeline
1200: Chimneys first
appear in Europe
1300: Fireplaces with
chimneys are built into
the walls of buildings

5. Heating Technology Timeline
1700s: Cast-iron stoves
are used to heat rooms
Late 1700s: Central
Heating reappears using
coal

6. Heating Technology Timeline
1800s: forced-air heating
1906: Electric heaters

7. Needs vs Wants
Needs: are things we must have to stay alive (food, water, air)
Wants: are things we would like to have (I-pods, cell phones,
TV’s)
In Canada we have some heat technology NEEDS.

8. Needs vs Wants
Standard of Living: A measure of how well
we live, including the level of technology that
we use in our daily lives

9. Heating Technology Timeline
Think about
microwaves!
What others can you
think of?

10. Controlling Heat
Why do we need to control heat?
Example: A furnace and a thermostat.
A furnace generates and transfers the heat from one area to
another.
A thermostat allows us to control and monitor that heat. If
it is too hot, we turn the thermostat down. If it is too cold,
we turn the thermostat up.

11. Sustainable
vs
Non-Sustainable

12. Sustainable
Sustainable: means something can be maintained or
used again and again
Examples of Sustainable Resources:
• Wind
• Water
• Wood

13. Non-Sustainable
Non-Sustainable: means something can NOT be
maintained or used again and again
Examples of Non-Sustainable Resources:
• Coal
• Oil
• Gas

14. Sustainable or Non-Sustainable
What about the sun?
