  • A boy buys two substances from a shop, both of the same mass. He finds the packet of one of the substances bigger than the other. Which packet do you think will he find weighing more and heavier to carry?
    Same mass so both will weigh the same.

  • 1litre of pure water is 1000g but in oil packets, we find 1 litre is 910g. What does it tell about the nature of the two liquid?
    the density of water > density of oil

  • An object has a mass of 10 grams and a volume of 5 ml. What will happen when the object is placed in water, and why?
    Sink slowly, because the density of 2 g/mL is greater than that of water
