Hannah heats a beaker of water using a burner, as shown in the diagram.
Which statement best describes the movement of water molecules in Hannah's beaker, represented by the arrows in the diagram?
a
Water molecules move slower near the bottom of the beaker where they are hotter, but then move faster as they cool and rise due to convection.
b
Water molecules move faster near the bottom of the water where they are hotter, but then move slower as they cool and rise due to radiation.
c
Water molecules move slower near the bottom of the beaker where they are hotter, but then move faster as they cool and rise due to conduction.
d
Water molecules move faster near the bottom of the beaker where they are hotter, but then move slower as they cool and rise due to convection.
