Heat Transfers

Front

What is convection?

Back

Convection is the transfer of heat through a fluid (liquid or gas) caused by the movement of the fluid itself. Hot fluid rises, while cooler fluid sinks, creating a circulation pattern.

Front

Give an example of convection in everyday life.

Back

An example of convection is when Jose cooks an egg in a pot of boiling water.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light. It does not require a medium to travel through.

Front

Provide an example of radiated heat for cooking.

Back

Grilling hot dogs over a campfire is an example of radiated heat.

Front

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.

Front

Give an example of conduction in action.

Back

When Sarah stirs her hot chocolate with a metal spoon, the spoon gets hot due to conduction.

Front

Explain what happens when you hold hands with someone warmer than you.

Back

The heat energy from your friend's hand transfers to your hand through conduction.

Front

What is the definition of heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another.

Front

What are the three main types of heat transfer?

Back

The three main types of heat transfer are conduction, convection, and radiation.

Front

How does convection work in the atmosphere?

Back

In the atmosphere, warm air rises and cool air sinks, creating wind patterns and weather systems.
