The mass density of Kerosene is: (1) more than water (2) equal to water (3) Less than water (4) None of the above

The mass density of Kerosene is: (1) more than water (2) equal to water (3) Less than water (4) None of the above
by

1 Answer

Answer :

(3) Less than water Explanation: Kerosene is lighter than water in terms of density. Density of kerosene is 820 kg /m3, means if you take 1000 liters of kerosene it would weight 820 kg. Whereas density of water is 1000 kg /m3 means if you take 1000 liters of water it would weight 1000 kg.
