Energy Unit Part 2: Thermal Energy Transfer

Front

What is the type of heat transfer that does not require physical contact between substances?

Back

Radiation

Front

In which form of heat transfer does energy transfer occur due to differences in density?

Back

Convection

Front

How is temperature best defined?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What type of thermal energy transfer can occur in gases, liquids, and solids?

Back

Conduction

Front

What is the direction of thermal energy transfer?

Back

Thermal energy transfers from warm objects to cool objects.

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to density differences.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves.

Front

What is the relationship between temperature and thermal energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance, which relates to its thermal energy.

Front

What happens to the density of a fluid when it is heated?

Back

When a fluid is heated, its density decreases, causing it to rise.
