• The butter and water will both become liquids.

• The butter will remain a solid, and the water will become a liquid.

• The butter and water will both remain solids.

• The butter will become a liquid, and the water will remain a solid.

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?

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

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

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

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

A student performs an experiment. The students wants to study the fastest way to dissolve sugar in tea. The student uses 50 milliliters of tea and adds 50 grams of sugar cubes for each trial. The student waits two minutes before making the observations shown in the table. How can the experiment be changed to be sure that as much sugar as possible has dissolved?

• Use larger sugar cubes in the 40 degree Celsius tea.

• Stir the tea constantly at all three temperatures.

• Use less water at all three temperatures.

• Use a larger cup to hold the 50 degree Celsius tea.
