What is convection?

• The movement of thermal energy through liquids and gas
• The movement of thermal energy through radiation
• The movement of thermal energy by touching another object
• The movement of thermal energy through conduction

Can energy be created or destroyed?

• It depends
• No
• Sometimes
• Yes

What is heat?

• The movement of sound waves
• The movement of light waves
• The movement of thermal energy between two objects
• The movement of electrical energy
