The correct answer to this question is B, II only, which states Add more sugar and heat the solution. Sugar dissolving in water is the process of solubility. It dissolves because of the energy which is given off. This energy is so significant that it breaks the bonds between the sugar and the water.

This process occurs with any solute and solvent. Other examples include salt. The sugar will dissolve in hot water because hot water has more energy than cold water. The energy from the hot water breaks the bonds down to dissolve the sugar. The molecules will also move faster.

It is a common experiment to put sugar in water and watch it dissolve. There must be an attraction between the two substances in order for one of them to dissolve. In this case, both water and sugar are attracted to each other which is why sugar dissolves in water. To be more specific, the atoms between the sugar causes the oxygen to have a negative charge and the hydrogen will have a positive charge.

These substances also depend on whether or not they are polar substances or nonpolar substances. If you wanted to add more sugar into a glass of water where sugar has already been dissolved in it, it would need to be heated in order for more sugar to dissolve.

Add more sugar and heat the solution to cause more sugar to dissolve in a saturated sugar water solution. So, the correct option is B. II only.

This is because heat increases the surface area and decreases the particle size. When we heat the solution, the sugar particles start moving rapidly and interacting with each other at a high temperature which adds more energy to the process.
