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. Example: Touching a hot stove.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warmer, less dense fluid rises while cooler, denser fluid sinks, creating a circulation pattern. Example: Warm air rising near a heater.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through. Example: The sun warming your skin.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state. Example: A book on a shelf has potential energy due to its height.

Front

What is the difference between conduction and convection?

Back

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

Front

What is an example of conduction in everyday life?

Back

An example of conduction is when you touch a metal spoon that has been sitting in a hot pot.

Front

What is an example of convection in everyday life?

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling warmth from a campfire or the sun without direct contact.

How does heat transfer affect weather patterns?

Back

Heat transfer through convection in the atmosphere helps create wind and weather patterns, influencing temperature and precipitation.
