true or false: when water which is used to dissolve glucose is heated from 25 degrees to 80 degrees the solubility of the glucose is increased.
true. Most, but not all, solids increase solubility in water with increased temperature. Most gases decrease solubility in water with higher temperatures.
True. When water is heated, the solubility of most solid solutes increases, including glucose. To understand why this happens, we can look at the concept of solubility and temperature.
Solubility refers to the maximum amount of solute that can be dissolved in a solvent at a given temperature. In the case of glucose, the solute, and water, the solvent, increasing the temperature of the water increases the solubility of the glucose.
This behavior can be explained by the fact that raising the temperature of a solvent increases the kinetic energy of its molecules. As a result, the water molecules move more rapidly and interact more effectively with the glucose molecules, breaking down the glucose-solute bonds. This process allows more glucose molecules to dissolve in the water, increasing the solubility.
Therefore, when water used to dissolve glucose is heated from 25 degrees Celsius to 80 degrees Celsius, the solubility of glucose in water is indeed increased.
