Question 34

Change of State and Vapours

The change in volume when 450kg of ice is completely melted is [density of ice = 900 kgm−3, density of water = 1000 kgm−3]

  1. A.0.05m3.
  2. B.0.45m3.
  3. C.4.50m3.
  4. D.0.50m3
Show the answer and explanation

Answer: A (0.05m3.)

Explanation

Volume of ice = 450/900 = 0.50 m3; volume of water = 450/1000 = 0.45 m3; change = 0.05 m3.
