4.8B Vocabulary Flashcard

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often referred to as heat energy.

Front

What is a thermal insulator?

Back

A thermal insulator is a material that does not conduct heat well, preventing the transfer of thermal energy.

Front

What is a thermal conductor?

Back

A thermal conductor is a material that allows heat to pass through it easily, facilitating the transfer of thermal energy.

Front

Give an example of a good thermal insulator.

Back

Wood is an example of a good thermal insulator.

Front

Give an example of a good thermal conductor.

Back

Metal is an example of a good thermal conductor.

Front

What is electrical energy?

Back

Electrical energy is the energy of charged particles, such as electrons, moving through a conductor.

Front

True or False: Metals are commonly used as conductors.

Back

True.

Front

What is the relationship between thermal energy and temperature?

Back

Thermal energy is directly related to the temperature of an object; as temperature increases, thermal energy increases.

Front

What is the role of thermal insulators in everyday life?

Back

Thermal insulators are used to reduce heat loss or gain, such as in building insulation and thermos containers.

Front

How does the structure of a material affect its ability to conduct heat?

Back

Materials with closely packed atoms or molecules tend to conduct heat better than those with loosely packed structures.
