The change in volume when 450kg of ice is completely melted is? [density of ice = 900 kgm−³; density of water = 100 kgm−³]

A. 0.50m³
B. 0.45m³
C. 0.05m³
D. 4.50m³

Correct Answer:

Option C – 0.05m³

Explanation

Vol. of ice = M/?D = 450/900 = 0.500m³
vol. of water = M/D” = 450/1000 = 0.450m³
∴ Difference in vol. = 0.500 – 0.450
= 0.05m³
