Energy & Heat Transfer

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm air rises while cool air sinks, creating a circulation pattern.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. Heat moves from the hotter object to the cooler one.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves. It does not require a medium, so it can occur in a vacuum.

What is the difference between conduction and convection?

Back

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

Front

What is an example of conduction?

Back

Holding a hot coffee mug; heat transfers from the mug to your hands.

Front

What is an example of convection?

Back

Warm air rising from a heater and cool air sinking, creating a circulation of air.

Front

What is an example of radiation?

Back

Feeling the warmth of the sun on your skin, which is heat transferred through electromagnetic waves.

Front

What is thermal energy?

Back

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

Front

How does heat transfer affect weather patterns?

Back

Heat transfer through convection in the atmosphere helps create wind and weather systems.

Front

What is insolation?

Back

Insolation is the amount of solar radiation received by a surface, influencing temperature and climate.
