Heat Transfer

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when faster-moving particles collide with slower-moving ones, transferring energy.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases). Hot fluid rises while cold fluid sinks, creating a circulation pattern.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation. It does not require a medium to travel through.

Front

What is heat?

Back

Heat is the transfer of thermal energy from a hotter object to a cooler one.

Front

What happens to gas particles when they are heated?

Back

When gas particles are heated, they move faster and spread apart, causing the gas to expand.

Front

What is thermal energy?

Back

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

Front

What is temperature?

Back

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

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and burning your hand.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.
