  • Q14
    In our heat transfer lab, the plastic bag lifted up off the toaster and floated to the ceiling. Why?
    Convection. The contact between the toaster and the table made it happen.
    Convection. The heat from the toaster made the air in the bag more dense, so it began to float up.
    Radiation. The waves of energy from the toaster hit the bag and made it less dense.
    Convection. The heat from the toaster made the air in the bag less dense, so it began to float up.
