The change in volume when 450kg of ice is completely melted is
[density of ice = 900 kgm-3, density of water = 1000 kgm-3]
[density of ice = 900 kgm-3, density of water = 1000 kgm-3]
0.50m3
0.45m3
0.05m3
4.50m3
ব্যাখ্যা
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
vol. of water = M/D" = 450/1000 = 0.450m3
∴ Difference in vol. = 0.500 - 0.450
= 0.05m3
