  • Q4
    4. What is the primary factor determining the amount of heat required to change a substance's state (e.g., from solid to liquid)?
    The surface area of the substance.
    The specific latent heat of the substance.
    The rate of temperature change of the substance.
    The specific heat capacity of the substance.

  • Q5
    5. What is meant by 'thermal equilibrium'?
    The transfer of heat between two substances occurs at a constant rate.
    A substance maintains a constant temperature over time.
    The temperature of a substance indicates how much heat it has absorbed.
    Two substances in contact with each other reach the same temperature.

  • Q6
    6. A blacksmith heats a piece of iron to shape it. Which statement explains why the iron becomes easier to work with when heated?
    The heat energy converts some of the iron to a liquid state, making it easier to mould.
    The iron absorbs heat energy, making its molecules expand and move more freely.
    The heat energy weakens the bonds between iron molecules, reducing its strength.
    The heat energy causes the iron to undergo a chemical change, making it more malleable.

  • Q8
    8. Why do you feel warmer when standing near a bonfire compared to standing the same distance away from a hot stove?
    The bonfire produces more heat energy than the stove.
    The air around the bonfire is hotter than the air around the stove.
    The bonfire produces more smoke and particles, which trap heat.
    The bonfire emits more heat radiation than the stove.

  • Q9
    9. Explain why you feel a burning sensation when you touch a hot metal object.
    The metal radiates heat energy, which is absorbed by your hand.
    The metal is a good conductor of heat, allowing for a rapid transfer of heat to your hand.
    Your hand and the metal object reach thermal equilibrium, causing a burning sensation.
    The metal object is at a higher temperature, so heat flows into your hand.

  • Q10
    10. Imagine you have two identical metal rods, one painted white and the other painted black. Both rods are exposed to direct sunlight for an hour. Which rod will be hotter? Explain why.
    The temperature difference will be negligible as sunlight is not a significant heat source.
    The black rod will be hotter because it absorbs more sunlight.
    The white rod will be hotter because it reflects more sunlight.
    Both rods will be the same temperature because they are made of the same material.
