  • Which physical quantity is different? Why?
    Mass is different because the densities of kerosene and water are different
  • A square board of side 5 cm has area of ___________
    25 sq. cm
  • A plot measuring 2 km in length and 0.5 km in breadth has area of ________
    1 sq. km
  • What can you tell about the density of the cherry tomato?
    It is more dense than dish soap but less dense than milk
  • Calculate the volume of the hammer given that the volume of the liquid is measured in ml
    4 ml = 4 cu. cm
  • Identify the volume of liquid (if the scale used is ml)
    44 ml
  • What is the difference between capacity and volume of a liquid?
    Capacity is the inner volume of a container (the maximum volume of liquid it can hold). Volume is the space occupied by the amount of liquid inside a container
  • In the given image, calculate the volume of the middle arrangement (given that the sides of each cube is 1 units i,e b = 1)
    Volume of 1st arrangement = 27 cu. units, volume of 1 small cube = 1 cu. units. Therefore, volume of second arrangement = 27 - 1 = 26 cu. units
  • Which liquid is the least dense?
    Liquid A
  • What will happen if you add 1 tbsp salt in one cup of water and 3 tbsp salt in another similar cup of water? (the volume of water is the same)
    The cup with 3 tbsp salt will have more density
