What is convection?

Back

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

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.

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.

How does convection occur in a swimming pool?

Back

In a swimming pool, warm water near the surface rises while cooler water sinks, creating a circulation of water.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot cup of coffee.

Front

How does radiation keep a lizard warm under a lamp?

Back

The heat from the lamp radiates towards the lizard, warming it without direct contact.

Front

What happens to an egg on hot pavement?

Back

The pavement conducts heat to the egg, cooking it due to direct contact.

Front

What is the role of convection in weather patterns?

Back

Convection helps distribute heat in the atmosphere, leading to wind and weather changes.

Front

What is an example of radiation in nature?

Back

The heat from the sun reaching the Earth is an example of radiation.

How does convection affect cooking?

Back

In cooking, convection ovens circulate hot air around food, cooking it evenly.
