What is an example of a convection current?
heating up water 
Explain a convection current
particles moving in a circle: warming, rises up, cooling, sinking, then warming again

Convection current
True or False: Hot air rises since it is less dense.
True. Hot air rises Think about hot upstairs is sometimes warmer than downstairs
cool air is (more or less) dense than hot air
cool air is more dense than hot air
True or False: Hot soup warming a cold spoon is an example of conduction.
True
True or False: Convection is the transfer of thermal energy when objects touch?
False! Convection is the transfer of thermal energy as matter moves
