13.3 Using Heat

I. Home Heating Systems Forced-Air System-the most common type of heating system. Fuel is burned in a furnace & heats air. 2. A fan blows the heated air through pipes called ducts 3. Ducts lead to open vents in a room.

B. Radiator systems-a closed container that contains hot water or steam. The heat is transferred to the air by conduction. 2. Some radiators are electric a. Metal coils heat up and transfer heat to the surrounding air mainly by radiation.

C. Electric heating systems-are placed in floors and heat is transferred by conduction. Sometimes hot water will be used instead of heating cables.

D. Traditional Korean homes use what’s known as an “ondol” heating system. Homes would be built high off the ground and a fire pit would be at one end of the house.

II. Solar Heating Energy from the sun is called Solar Energy. B. Passive Solar Heating-provides heat to a room. Uses no mechanical parts.

C. Active Solar Heating-uses devices called solar collectors. Solar Collectors-a device that absorb radiant energy from the Sun.

III. Using Heat To Do Work Internal combustion engine-fuel is burned inside the engine in chambers, or cylinders. Engines typically have 2, 4, 6, or 8 cylinders. More cylinders = more POWER

Parts of an internal combustion engine

B. Engines have 4 movements or “strokes”

Intake stroke-fuel-air mixture put into cylinder by valve.

2. Compression stroke-fuel compressed and ignited by spark plug.

3. Power stroke-ignited fuel-air mixture expands and pushes the piston down, producing power.

4. Exhaust Stroke-burnt gases exit cylinder

C. Engines become hot due to buildup of thermal energy and friction.
