Thermal energy from inside the Earth's crust can be harnessed as a useful thermal energy source.
Volcanoes, hot springs and geysers are example of this type of thermal energy source. This type of thermal
energy is ...

1

The thermal efficiency of a building’s design can be measured by how well it prevents ...

1

Solar collectors are used to capture the Sun’s energy. These collectors are filled with ...

1

Solar cells are arranged in panels, which are connected in a series, and then placed to capture and store the
Sun’s energy in low voltage batteries. The panels are connected in a series to form what is called a solar ...

This illustration shows the inside workings of a thermostat.
The bimetallic strip, made of two different metals that expand and contract at different rates, enables the coil to act as a ...

1

Relative temperature for a comfortable room is maintained by using a thermostat, that is connected to a central heating system. The relative temperature of a comfortable room is ...

1

Two types of heating systems in a house help to maintain heat flow where it is needed. The type of heating system that provides heat from a single, central source such as a furnace is called ...

1

Air that is heated by burning fuel in a furnace and then sent throughout the house through ducts to a register
in every room is an example of this type of heating system ...

Basic parts of a cooling system are: a storage tank, a compressor, a freezer unit, condenser coils, and a ...

1

A natural insulator helps to keep animals, such as polar bears and seals, warm in frigid water. This natural insulator forms a protective layer to help keep heat from leaving the body. This natural insulator is ...

1

A material’s ability to transfer heat by conduction is reflected by its thermal ...

1

Stone and brick are excellent insulators, but are not widely used because they are too expensive. The most common type of insulation that provides a layer of paneling between the outer walls and the siding is ...

1

In an average house heat is lost (transferred to the outside) in five major places. The least amount of heat is lost through the ...

1

To determine where heat is lost in a building, contractors can ask a photographer to take this type of photo of the house.

1

Insulators are rated by their insulating ability. R-value is given to each material that is used in the
construction of a building. The best insulating product would have a ...
