Question

Use the graph to identify the number, letter, or word that completes each statement.

• The solubility of Solute D
as temperature increases.
• The solubility of Solute
increases the most as temperature increases.
• The solubility of Solutes C and D is the same at
°C.
• As the temperature increases from 0 to 100, which solution’s solubility only changes by about 5 grams? Solution letter:

Answer 1

I don't see the graph attached. Could you upload the image or give the numerical values (solubility in g per 100 g water at several temperatures) or a brief description of each curve (which letters slope up, down, cross, or are nearly flat)?

How to get each answer once I have the graph:
- "The solubility of Solute D ___ as temperature increases." — look at Solute D's curve: if it rises from left to right write "increases"; if it falls write "decreases"; if nearly horizontal write "stays about the same."
- "The solubility of Solute ___ increases the most as temperature increases." — find which letter's curve has the steepest upward slope overall (biggest rise in g from low to high temp).
- "The solubility of Solutes C and D is the same at ___ °C." — find the temperature where the C and D curves intersect; that x-value is the answer.
- "As the temperature increases from 0 to 100, which solution’s solubility only changes by about 5 grams? Solution letter:" — read each curve at 0°C and 100°C, compute the difference; pick the letter whose absolute change is approximately 5 g.

If you upload the graph I’ll read it and give the four specific answers.
