"Sources of Thermal Energy"

fossil fuels

Greenhouse effect
Products that are released form the burning of fossil fuels is a greenhouse
gas, traps heat energy in our atmosphere

In a liquid, the particles are moving very quickly. At the surface, some of the
particles are able to escape into the air, causing evaporation

"Sources of Thermal Energy"

energy from the sun. The sun’s energy is clean and will not run out.

A device that transfers thermal energy from one location to another
at different temperatures.

"Sources of Thermal Energy"

volcanoes, hot springs and geysers are indications
of extremely hot materials in side the earths crust.

"Sources of Thermal Energy"

mechanical forces that push or pull object often
release thermal energy.

"Sources of Thermal Energy"

energy is stored in chemical bonds that hold the
particles together.

-Burning ourselves on hot utensils (us). Forest fires (our environment).
-Burning houses (our belongings).
-They can also pollute the
environment, by leaking into the groundwater and soil.

"Sources of Thermal Energy"

can be produced by hydro-electric dams, falling water.

Energy Transfer system ( Pick 2 )

Higher the RSI value of a substance the better the insulating value

"Sources of Thermal Energy"

anything that provides energy in a useful form.
Chemicals from plants and other organisms that die and decompose.

Liquids that evaporate easily at low temperatures to remove thermal
energy from food. As it evaporates it absorbs the thermal energy
form the food so it cools down. The warmed gas is then compressed
and releases the thermal energy into the room.

When the temperature goes up the particles __________. When the
temperature goes down the particles __________.

-Carbon dioxide is released from the burning of fossil fuels is a
greenhouse gas.
-Sulfur dioxide released when coal and natural gas are burned.
-Carbon Monoxide produced when a fire burns without enough oxygen.

-Saving Fuel
-Insulation, programmable thermostats
-Provide many ways to conserve energy and save money.
-Recirculation hot water system
-Saves energy and produces instant hot water at all times.

"Sources of Thermal Energy"

trees, crops

Sources of Thermal Energy


energy from moving air. It is the result of solar energy heating air.
