Review: Convection, Conduction, Radiation

Front

What is the only type of thermal energy transfer that can occur where no molecules are present?

Back

Radiation

Front

What form of energy transfer occurs when a metal pan is heated on the stove?

Back

Conduction

Front

What is the primary method of heat transfer that causes a pot of water to boil?

Back

Convection

Front

Which material is considered the best conductor of heat?

Back

A metal pan

Front

What is the term for heat transfer that occurs from direct contact between molecules?

Back

Conduction

Front

What is convection?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat energy is passed from one molecule to another.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

Front

How does convection differ from conduction?

Back

Convection involves the movement of fluids and the transfer of heat through that movement, while conduction involves direct contact between materials.

Front

What role does temperature play in convection?

Back

Temperature differences cause changes in fluid density, leading to the movement of warmer, less dense fluid rising and cooler, denser fluid sinking.
