Conduction

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.

• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.

• When heat transfers from objects that are touching.

• When heat transfers through the heater or AC in your house.

The transfer of heat energy by direct contact, or touch, is __________________?

• radiation

Which is the 
best example 
of conduction? 

• boiling a pot of water

• feeling heat from a fireplace 

• a hot air balloon rising and falling 

• touching a hot  handle and  getting burned

The transfer of energy through matter by the direct contact of particles is called​ (a)   .

• conduction

• convection

• radiation

• kinetic energy

Answer explanation

Conduction is the transfer of energy through matter by direct contact of particles, making it the correct choice in this context.
