Science Ch 1 Les 4 - Heat Energy Flashcard (SAVVAS)

Front

What is heat energy?

Back

Heat energy is a form of energy that is transferred between objects due to a temperature difference.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact of materials.

Front

What is convection?

Back

Convection is the transfer of heat through liquids and gases, where warmer areas of a liquid or gas rise and cooler areas sink.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves, such as sunlight traveling through space.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, preventing heat transfer.

Front

Give an example of a good insulator.

Back

A towel is a good insulator because it traps heat and keeps things warm.

Front

What is an example of conduction in everyday life?

Back

Cooking hotdogs on a grill is an example of conduction.

Front

What is an example of convection in everyday life?

Back

Boiling water is an example of convection, as the hot water rises and cooler water sinks.

Front

What is the primary method of heat transfer from the sun to the Earth?

Back

The primary method of heat transfer from the sun to the Earth is radiation.

Front

What happens to particles in a material when it is heated?

Back

When a material is heated, its particles move faster and spread apart.
