Question

1 gram of ice is put into a container that already has 100 grams of liquid water in it. The 1 gram of ice melts into the water. Following the law of conservation of matter, the mixture is still 100 grams.

A. True
B. False

Answer 1

B. False

After the ice has melted into the water, the total mass of the mixture will be 101 grams, not 100 grams. This is because the ice adds an additional 1 gram of mass to the container.
