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?

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

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

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

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

• A. The contents of the glass are wet before and after the ice melts.

• B. The combined mass of the glass and its contents is the same before and after the ice melts.

• C. The combined mass of the glass and its contents is less after the ice melts.

Malik weighed an empty beaker. The beaker weighed 50 grams. Then Malik added 115 grams of water to the beaker. He placed the beaker of water in a freezer until the water became solid ice. Which prediction should Malik make about the ice in the beaker?

• The ice will weigh less than 115 grams. After the ice melts, the water will weigh less than 115 grams.

• The ice will weigh less than 115 grams. After the ice melts, the water will weigh 115 grams.

• The ice will weigh 115 grams. After the ice melts, the water will weigh less than 115 grams.

• The ice will weigh 115 grams. After the ice melts, the water will weigh 115 grams.

A group of students weighed a sealed jar full of heavy cream. Then they shook the jar until the cream separated, and then they weighed the jar again. Which of the following would BEST describe its weight?

• A. The jar will have gained weight because some liquid changed to a solid.

• B. The jar will have gained weight because shaking added energy to it.

• C. The jar will have lost weight because of friction from shaking the liquid.

• D. The jar will have kept the same weight because it did not gain or lose any matter.

• A. A mixture forms.

• B. A solution forms.

• C. A chemical change occurs.

• D. Thermal energy is used.
