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 solutions solubility only changes by about 5 grams? solution letter

Explanation:

Step1: Observe Solute D trend

By looking at the graph of Solute D, we can see that as the temperature increases, the solubility curve of Solute D goes downwards. So the solubility of Solute D decreases as temperature increases.

Step2: Compare slopes of curves

To find which solute's solubility increases the most as temperature increases, we compare the slopes of the solubility - temperature curves of all solutes. Solute E has the steepest upward - sloping curve, so its solubility increases the most as temperature increases.

Step3: Find intersection point

To find the temperature at which the solubility of Solutes C and D is the same, we look for the point of intersection of their curves. The intersection occurs at approximately 25°C.

Step4: Calculate solubility change

For each solute, we calculate the difference in solubility at 0°C and 100°C. For Solute B, the solubility at 0°C is around 20 grams and at 100°C is around 25 grams, a change of about 5 grams.

Answer:

• decreases
• E
• 25
• B
