thermal expansion

What is Thermal Contraction 

• A Potato
• A decrease in a materials  volume when its temperature decreases 
• The movement of fluids in a cycle because of convection 
• A material through which  thermal energy does not flow easily.

What is Thermal expansion?

• The transfer of thermal energy between materials by the collisions of particles 
• Is a decrease in a materials volume when temperature decreases 
• An increase in a materials volume when temperature increases
• Chicken fried rice

What is the definition of CONVECTION

• When heat transfers through waves.
• When heat transfers from objects that are touching.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• Heat traveling from the sun

Warm air rises and the cool air sinks demonstrates this type of heat transfer. 

• conduction
• convection
• radiation
• Insolation
