Stuart measures 10 grams of water into a pan and freezes it. A day later he takes it out of the freezer and observes that it is larger than before. What is the mass of the ice?
a
10 grams
b
11 grams
c
20 grams
d
25 grams
b) 11 grams
When water freezes, it expands in volume which means that the mass of the ice will be slightly more than the mass of the water before freezing.
