The chart shows the solubility of different substances.
A 3-column table with 6 rows. The first column labeled solute has entries sugar, sugar, salt, salt, nitrite salt, nitrite salt. The second column labeled temperature has entries 20 degrees C, 100 degrees C, 20 degrees C, 100 degrees C, 20 degrees C, 100 degrees C. The third column labeled grams per 100 grams of water has entries 204, 487, 36, 39, 81, 160.
Which statement is represented by the graph?
