What is the definition of CONDUCTION?
When heat is transferred by electromagnetic rays of light.
A hot liquid or air that expands, becomes less dense, and rises or becomes more dense, and sinks.
When heat transfers by objects that are physically touching.
When heat transfers by the fluid movement of a liquid or a gas.
What is the definition of RADIATION
Hot liquid or air that expands, becomes less dense, and rises or becomes more dense, and sinks.
When heat is transferred by electromagnetic rays of light.
When heat transfers by objects that are physically touching.
When heat transfers by the fluid movement of a liquid or a gas.
Which of the following is an example of convection?

Your hands being warmed by a hot coffee mug is _____.
radiation
conduction
friction
convection
How is heat from the sun and heat from a campfire alike?
They move by radiation.
They move by convection.
They move by conduction.
They are solar energy.
Explain the difference between conduction and convection.
Conduction involves heat going in all directions while heat rises with convection.
Heat moves in all directions for convection, but it rises for conduction.
Heat rises for convection and travels thru liquids and gases. Conduction travels thru solids and liquids but must be physically touching.
Thermal energy travels thru solids for both conduction and convection; however, conduction involves direct contact.
When warm air rises and the cool air sinks, it represents __________.
conduction
convection
radiation
