What is conduction?

Back

Conduction is the transfer of heat from one object to another through direct contact.

Front

What is convection?

Back

Convection is the transfer of heat through a fluid (liquid or gas) where hot fluid rises and cold fluid sinks.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

How does heat transfer in conduction?

Back

Heat transfers in conduction when two objects are touching, and heat moves from the hotter object to the cooler one.

Front

How does heat transfer in convection?

Back

In convection, heat is transferred by the movement of fluids; hot fluid rises and cold fluid sinks, creating a circulation pattern.

Front

How does heat transfer in radiation?

Back

In radiation, heat is transferred without the need for a medium; it can occur through empty space.

Front

What happens to a substance when it is heated?

Back

When a substance is heated, its particles gain energy, move faster, and may expand.

Front

What is an example of conduction?

Back

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

Front

What is an example of convection?

Back

An example of convection is the warm air rising from a heater and circulating in a room.
