Thermal

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

A bimetallic strip is made up of _____________________ welded together.

• two metals of the same kind 
• two different metals that expand and contract unequally
• two different metals that expand and contract equally

What is Thermal Contraction

• The movement of particles.

• 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.
