The 20 questions

  1. What do the chemicals inside a simple chemical cell do?

    • React to produce electricity
    • Absorb thermal energy
    • Neutralise each other completely
    • Decompose into pure elements

  2. What two main factors determine the voltage produced by a simple chemical cell?

    • Beaker size and shape
    • Electrode and electrolyte type
    • Room temperature and pressure
    • Wire length and thickness

  3. What must be connected to an electrolyte to make a simple cell?

    • Two identical metals
    • Two non-metal rods
    • One metal and plastic
    • Two different metals

  4. How are individual cells arranged to construct a battery with greater voltage?

    • Cells placed separately apart
    • Cells connected in series
    • Cells connected in parallel
    • Cells arranged in a loop

  5. Why do non-rechargeable cells eventually stop producing electricity?

    • Reactants are used up
    • Metals melt away
    • Electrolyte freezes solid
    • Voltage becomes too high

  6. Which type of battery is alkaline?

    • Fuel cell
    • Rechargeable
    • Non-rechargeable
    • Solar cell

  7. Why can rechargeable cells and batteries be recharged?

    • Reactions are reversible
    • Voltage increases over time
    • Reactants never run out
    • Electrolytes are solid metals

  8. Two cells are connected in series. How does the voltage compare with one cell?

    • Lower
    • Zero
    • Greater
    • The same

  9. Which pair of metals would give the greatest voltage in a cell?

    • Copper and silver
    • Zinc and iron
    • Iron and iron
    • Magnesium and copper

  10. In a zinc and copper cell with acid, which electrode is the negative electrode?

    • Both
    • Copper
    • Neither
    • Zinc

  11. Safe and careful use of which substances is needed in cell practicals?

    • Gases only
    • Radioactive materials
    • Solids only
    • Liquids

  12. Why does a magnesium-copper cell give a higher voltage than zinc-copper?

    • Larger surface area
    • Higher solution concentration
    • More electrolyte volume
    • Greater reactivity difference

  13. What feature is shared by rechargeable and non-rechargeable cells?

    • Use chemical reactions
    • Can be recharged
    • Never run out
    • Use external fuel

  14. Which metal pairing would produce the smallest voltage among these?

    • Copper and silver
    • Magnesium and zinc
    • Zinc and copper
    • Magnesium and copper

  15. What is the main function of the electrolyte in a cell?

    • Increases cell temperature
    • Transfers electrons directly
    • Acts as solid fuel
    • Allows ions to move

  16. In a zinc-copper cell, which metal loses electrons?

    • Both metals
    • Zinc
    • Copper
    • Neither metal

  17. Why does a non-rechargeable battery stop working after extended use?

    • Reactants are depleted
    • Electrodes melt away
    • Electrons run out
    • Reactions reverse

  18. How does connecting extra cells in series affect battery voltage?

    • Stays exactly the same
    • Stops all current flow
    • Decreases total voltage
    • Increases total voltage

  19. A simple cell generates electricity from which kind of energy store?

    • Nuclear energy
    • Sound energy
    • Gravitational energy
    • Chemical energy

  20. What is a major environmental disadvantage of non-rechargeable batteries?

    • Depletes ozone layer
    • Produces greenhouse gases
    • Creates chemical waste
    • Causes radioactive leaks
