The density of water is 1g/cm\(^3\) while that of ice is 0.9g/cm\(^3\). Calculate the change in volume when 90g of ice is completely melted.
A
9cm\(^3\)
B
90cm\(^3\)
C
0cm\(^3\)
D
10cm\(^3\)
Verified Correct Answer: D.
Physical Principles & Numerical Solution
Answer: D. 10cm³
(Volume ice = \(\frac{90}{0.9}\) = 100 cm\(^3\);
volume water = \(\frac{90}{1}\) = 90 cm\(^3\);
change = 10 cm\(^3\) decrease.)
