Describe the transfer of heat energy and give examples of each Flashcards
What are the ways that heat can be transferred?
conduction, convection and radiation
What is conduction?
When two objects are directly touching each other and heat molecules are transferred between the objects.
What is an example of heat being transferred by conduction?
For example; when you touch a hot cup of tea and your hand heats up because the heat is being conducted by the cup to your hand.
When two objects are directly touching each other and heat molecules are transferred between the objects. is an example of which way heat can be transferred ?
Conduction
What is convection?
The transfer of heat from one place to another due to moving gases or liquid.
What is an example of heat being transferred by convection?
The steam coming from a hot drink shows the heat of the drink being carried away by the air and if you put your hand above the cup the heat goes into your hand.

Convection
What is radiation?
The flow of heat between objects that are not in contact with each other the heat ‘radiates’ or spreads out.
The flow of heat between objects that are not in contact with each other the heat ‘radiates’ or spreads out. is an example of which way which heat can be transferred?
An example would be heat traveling for the sun to Earth.
Heat traveling for the sun to Earth. is an example of which way heat can be transferred?
Radiation
