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.
Look at the data in the picture.
What conclusion is BEST supported by the data?
A. Sugar dissolves best at 22 degrees Celsius.
B. Sugar dissolves best at 60 degrees Celsius.
C. Sugar dissolves fastest between 22 degrees Celsius and 45 degrees Celsius.

A type of cold pack has two separate sections inside. One section contains a liquid and the other section contains a powder. When the cold pack is squeezed, the section that holds the liquid breaks. When the liquid combines with the powder, the pack becomes very cold.
Which is the BEST explanation why the temperature of the pack decreases when the liquid and powder combine?
A. A mixture forms.
B. A solution forms.
C. A chemical change occurs.
D. Thermal energy is used.
A student poured five different clear, colorless liquids into five different beakers. Each beaker was half-filled with the liquid. The student added 1 gram of a white powder and stirred each mixture. The student's observations are recorded in the data table.
In which two mixtures was a new substance formed?
Mixture 1
Mixture 2
Mixture 3
Mixture 4
Mixture 5
Students completed four investigations where they combined two different substances.
Which investigation shows evidence that the chemical properties of the substances changed?
A. Vegetable oil coats the surface of lettuce when oil and lettuce are combined.
B. Salt dissolves in water when salt and water are combined.
C. Sand sinks in water when water and sand are combined.
D. Bubbles form when baking soda and vinegar are combined.
The weight increases since there are more pieces of paper.
