There are different characteristics for each of the states of matter. Which statement describes a difference between liquids and solids?

• Temperature can change a solid to a liquid, but it cannot change a liquid to a solid.

Robert wants to find out which ball has the greater mass: soccer ball or basketball. He put the soccer ball on the balance. He places a 650-gram (g) block on the other side of the balance and observes the position of the balance. He then repeats the same test with the basketball. The results of his test are shown above.

Which of the following statements describes what Robert observed?

• The basketball has more mass than the soccer ball.

• The soccer ball has more mass than the basketball.

• The soccer ball and the basketball have equal masses.

• The block has more mass than either the soccer ball or the basketball.

Elizabeth has two 10-gram samples of sea salt. One sample is finely ground into thousands of tiny grains of salt. The other sample is a single block of salt crystals. Sofia tries to dissolve each sample in a separate glass of water. Which sample will dissolve first?

• The finely ground sample, because it has more surface area.

• The single block, because it has more surface area.

• The single block, because it has less surface area.

• The finely ground sample, because it has less surface area.
