Which of the statements represents a correctly worded hypothesis?
a. If sugar is a polar substance and solutes can dissolve in solvents that are like themselves, then adding sugar to water will allow the sugar to dissolve at a faster rate.
c. If increasing the temperature of a solvent increases the solubility of solutes in it, then increasing the temperature of water will allow more sugar to dissolve in it.
d. Substances with bubbles have more motion, so boiling water will dissolve more sugar than cold water because of the bubbles.
e. The solubility of sugar is directly proportional to the amount of energy that water contains, so sugar will dissolve faster in water that is warmer.
