if youre asking if temperature affects the rate of solubility of sugar in water then the answer is yes.

sugar is soluble in water because it reacts with the water molecules and forms bonds with them.
the molecules of water at a higher temperature are moving faster than those that are at room temperature or lower. so the chances that the water molecules will react with the sugar molecules is of course higher.
as a result, rate of solubility will also increase.

the same goes for stirring. if you stir a beaker of water with sugar granules it in, the sugar will dissolve faster than a beaker that is not stirred. this is again because the water molecules (and the sugar molecules) are now moving faster than those in the beaker that is not stirred. so the chances that the water molecules will react with the sugar molecules is of course higher.
as a result, rate of solubility will also increase.

i hope this has put your queries to rest.
have fun with chem. its really not so bad once you get the hang of it.
cheers.

The amount of sugar (I guess you meant sucrose, table sugar) that can be dissolved in water stronfly depends on temperature. I guess that dependence comes from the fact that at higher temperature molecules move faster and it also has to do something with interactions between molecules (of sugar and water).
Not always is like that. For example the dissolution of sodium chloride shows almost no temperature dependence while some salts are more soluble at lower temperatures than at higher (example is manganese sulphate). But that has its roots in ionic structure of salt (sucrose is molecular crystal) and in net energy.
Hope I've been of any help.

Of course, It does. During dissolution of sugar the solid sugar molecules that are bonded to each other breaks up and forms new bonds with water molecules -Hydrogen bonds. Sugar is basically a poly saccharide that has many Hydroxyl groups suitable for H-bond formation. The higher the temperature the higher the rate of collision of water molecules with sugar molecules and hence greater the rate of formation of Hydrogen bonds. The grater the posibility of heteromolecular interactions the greater the solubility.

Hot water will hold more sugar. When you heat up the water the molecules are farther apart therefore allowing more sugar molecules to enter. Thats why sweet tea is always sweeter at the bottom of the pitcher, as the tea cools off it releases the sugar that then settles to the bottom.

Temperature is one of the factors that affect solubility. You should have noticed that salts also dissolve more at higher temperatures and salts crystallize as temperature drops. Probalby because at higher temperatures, the K.E. of the constituent molecules is increased and there is expansion ( resulting to more intermolecular spaces). Looking at the opposite, liquids tend to solidify as temperature drops and as intermolecular space reduces, dissolved solutes tend to crystallize. Ok?

Yes, you can add more sugar into hot water. I think that this is because you are exciting the molecules. I am not exactly sure, but I just know from experience that boiling water hold more sugar.

I agree with Kish. Too bad I can't rate people. So yes, increasing the temperature does increase the solubility of sugar. =)

No, anything dissolves by bumping molecules.

yes
higher the temperature more the energy(kinetic energy of the particles) available
