Heat and Temperature

The heat from a lamp allows a lizard to remain warm. This is an example of which type of heat transfer?

• radiation
• conduction
• convection
• insulation

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.

What is the definition of CONVECTION

• When heat transfers through waves.

• When heat transfers from objects that are touching.

• warm fluid rises; cool fluid sinks

• Heat traveling from the sun

What is the BEST example of a conductor? 

• A wooden block
• A ceramic mug
• A glass cup
• A metal bowl

A measure of the average amount of kinetic energy of the particles in the object.

• energy
• expansion
• temperature
• heat
