Hannah heats a beaker of water using a burner, as shown in the diagram.

• 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.

• 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.

• 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.

• 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.

The diagram shows a nuclear reaction.

• fusion, because the reaction released energy

• fission, because the reaction absorbed energy

• fusion, because the reaction formed heavier nuclei

• fission, because the reaction formed lighter nuclei

How does the combination of deuterium and tritium during fusion change the nuclei?

• Two lighter nuclei form a lighter nucleus and release energy.

• Two lighter nuclei form a nucleus with fewer protons and release energy.

• Two lighter nuclei form a heavier nucleus and release energy.

• Two lighter nuclei form a nucleus with fewer electrons and release energy.
