According to the graph below, what happens to the density of a substance as its salinity increases (as you move up on the y-axis)?  (Helpful tip: pick at least 2 salinities and find their densities on the graph.  Compare.)

• As salinity increases, density stays the same.
• As salinity increases, density decreases.
• As salinity increases, density also increases.

According to the graph below, what happens to the density of a substance as its temperature increases (as you move up on the y-axis)?  (Helpful tip: pick at least 2 temperatures and find their densities on the graph.  Compare.)

• As temperature increases, density stays the same.
• As temperature increases, density decreases.
• As temperature increases, density increases.
