•Veronica weighed an empty bowl and recorded its mass. Then she placed three ice cubes in the bowl and weighed it again. After the ice melted, she recorded the mass of the bowl and the water. She put the data in a table.

•

• What conclusion should Veronica make from her observations?

Ice and Water Experiment

Objects Mass

empty bowl            110 grams

bowl and ice cubes 153 grams

bowl and water      153 grams

a)

•A) The masses of the water and the ice were both 43 grams, so the amount of matter did not change.

b)

Some of the water spilled because the mass of liquid water should have been greater than the mass of solid ice

c)

There was an error in weighing the ice because the mass of liquid water should have been less than the mass of solid ice.

d)

•The masses of the water and the ice were both 153 grams, so the amount of matter did not change.
