Making solutions
Solutions are mixtures that are very common in our daily lives. A solution is composed of a solute and a solvent.
A student conducted an investigation using 50 milliliter of distilled water and 5 grams of table salt. The water for each test was brought to a certain temperature before the salt was added. The data from the investigation are shown in the graph.
Which conclusion best describes the data in the graph?
Increasing the amount of solvent increases the temperature of a solution
Increasing the temperature of the solute increases the amount of the solution
the amount of solute in a solution determines the time needed for the solute to dissolve in the solvent
A decrease in the temperature of a solvent increases the time needed for a solute to dissolve in a solvent

Josh decided to mix some vinegar with baking soda. He knew that a reaction occurred because he made careful observations. He noted that the mixture started to foam up and bubble, and it was white in color. How did Josh know that a chemical reaction occurred?
He was sure a reaction occurred because of
the color of the mixture
the smell of the vinegar
the volume of the mixture
the formation of a gas
Franklin stores a gallon of milk in the refrigerator. Three weeks later, he notices that the milk has frozen on the top layer and also smells strongly of a sour odor. Which statement justifies that a physical change has occurred in the milk?
There is less milk since some of it froze.
There is a bacterial culture growing in the milk causing the sour smell.
The frozen layer on top of the milk can melt into liquid when left at room temperature.
Some of the milk sugar has been lost, leading to a more sour smell and taste
