Conduction, Convection, & Radiation

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

Give an example of convection in everyday life.

Back

An example of convection is the boiling of water in a kettle, where hot water rises and cooler water sinks.

Front

What is conduction?

Back

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

Front

Provide an example of conduction.

Back

An example of conduction is an ice cube melting in a person's hand, where heat is transferred from the hand to the ice.

Front

What is radiation?

Back

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

Front

Give an example of radiation in nature.

Back

An example of radiation is the heat from the sun warming the Earth.

Front

How does temperature affect particle movement?

Back

As temperature increases, the particles move faster, resulting in greater thermal energy.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What role does density play in convection?

Back

In convection, warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circulation pattern.
