Front

How does conduction occur?

Back

Conduction occurs when heat is transferred through direct contact between materials.

Front

What is the role of convection currents in heating a room?

Back

Convection currents help distribute warm air throughout a room, allowing for even heating.

Front

What is the difference between conduction and convection?

Back

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