Conduction, Convection, and Radiation

Front

The transfer of energy through matter by the direct contact of particles is called _____________.

Back

Conduction

Front

__________ is the transfer of energy in the form of electromagnetic waves.

Back

Radiation

Front

Conduction can occur in solids, liquids, and gases. Why are solids and liquids better conductors than gases?

Back

Solids and liquids have more closely packed particles than gases.

Front

Which type of energy transfer does not require matter?

Back

Radiation

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases) caused by differences in temperature and density.

Front

What is the primary mechanism of heat transfer in fluids?

Back

Convection.

Front

In which state of matter does conduction occur most effectively?

Back

Solids.

Front

What is the role of thermal conductivity in conduction?

Back

Thermal conductivity is a measure of a material's ability to conduct heat; higher thermal conductivity means better conduction.

Front

How does radiation differ from conduction and convection?

Back

Radiation does not require a medium to transfer energy, while conduction and convection do.

Front

What is an example of radiation in everyday life?

Back

The warmth felt from sunlight is an example of radiation.
