Question

Which solubility curve on the right best represents the data table on the left?
A 2-column table with 4 rows. Column 1 is labeled temperature in degrees Celsius with entries 0, 30, 60, and 90. Column 2 is labeled Sugar Dissolved in grams with entries 89, 110, 144, and 208.

A graph with Temperature in degrees Celsius ranging from 0 to 100 on the horizontal axis, and sugar per 100 grams of water on the vertical axis. An orange line curves down from about 0, 250 through 50, 125 to 100, 100. A blue line curves upward from 0, 95 to cross the orange line at 50, 125, and ends at 100, 250. A green line wavers across the entire graph between 90 and 95 grams of sugar.

Answer 1

The blue curve. The table shows solubility rising with temperature (0°C ≈ 89 g → 90°C ≈ 208 g); the blue curve is the only one that increases and passes near the given points (about 50°C ≈125 g). The orange decreases and the green is nearly constant, so they don't match.
