    Which best explains how bacon is fried on a stove burner?
    The bacon transfers heat directly to the pan, and the pan transfers heat directly to the stove burner.
    The stove burner radiates heat to the pan, and the pan radiates heat to the bacon.
    The stove burner transfers heat directly to the pan, and the pan directly transfers heat to the bacon.
    The bacon creates a convection current, the heat rises to the pan, and then rises to the stove burner.

    Which best explains why a hot air balloon floats?
    The heated air expands to fill the balloon. The air in the balloon is now lighter than the surrounding air, causing the balloon to rise.
    The heated air contracts to fill the balloon. The air in the balloon is now denser than the surrounding air, causing the balloon to rise.
