Heat Transfer

Front

What is heat transfer?

Back

The process of thermal energy moving from one object or substance to another due to a temperature difference.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves, which can occur through empty space.

What happens when an ice cube is placed in warm water?

Back

Heat is transferred from the warm water to the ice cube, causing it to melt. This is an example of conduction.

Front

Why does the sidewalk burn your feet in summer?

Back

The sidewalk absorbs heat from the sun and transfers it to your feet through conduction.

Front

What is an example of conduction in everyday life?

Back

Touching a hot stove and burning your hand.

Front

How does convection work in a pot of boiling water?

Back

Hot water rises to the top while cooler water sinks, creating a circular motion that transfers heat throughout the pot.

Front

What is an example of radiation?

Back

Feeling the warmth of the sun on your skin, even when you are not in direct contact with it.

Front

What is the difference between conduction and convection?

Back

Conduction requires direct contact between materials, while convection involves the movement of fluids.
