How does water temperature and stirring rate determine how fast a sugar cube dissolves?

What is meant by dissolving of sugar cubes?? For a sugar cube to dissolve, the bonds formed by the molecules with each other must break. That is the van der Waal bonds must break, not the valence bond(because otherwise, you cant call it a sugar molecule!).
And what is required for the bond to break?? Energy.
When we simply put a cube in water, very little parts of it may dissolve. That might be due to breaking of bonds using the energy from its fall(as it falls through the liquid, frictional heat develops; heat is a form of energy) or the heat from water(in case the temperature of water is greater than that of the cube). As I answer you question i think why sugar cube doesnt dissolve in air when air temperature is greater than that of the cube? It is because air isn't a solvent for solids!
Back to the answer to our question:
When you stir, you rise the water temperature. The kinetic energy is converted to heat energy.
When you rise the water temperature, the heat is equally distributed to the water and the cubes it contains. the cube takes the energy and the atoms start vibrating more intensely. this weakens the bond and when this is accompanied by the presence of molecules of a good solvent around it, the bonds break and the cube dissolves.

Does temperature affect the amount of sugar that dissolves in water?
Sugar that is dissolved in hot water, dissolves faster than sugar dissolved in cold water.
Which is affected most by increasing the temperature of the waterhow fast salt dissolves or how fast sugar dissolves?
it would have to be how fast the salt dissolves because a non polar sugar would not dissolve in water.
How do you make make a sugar cube dissolve at the fastest rate?
Crushing the sugar cube allows more surface area with the water that hydrates (dissolves) the sugar molecules. Therefore, it will dissolve faster. Stirring helps.
What is the effect of temperature and stirring on solubility of sugar?
These effects are the same when dissolving anything into anything. Stirring, or motion, is the key. Stirring plays a role because it is motion in the solvent at the macro level. The temperature of the solvent (water) plays a role because the higher the temperature the more motion in the volume at the molecular level.
How does stirring make sugar in water dissolve quicker?
Stirring enhances not only sugar dissolving in tea, but the same phenomenon applies every time a solid is dissolved in a solvent (the liquid phase). Let's look at what happens if a sugar crystal dissolves in tea: The sugar molecules leave the crystal and enter into the tea surrounding it. After some time you have a high concentration of sugar molecules just next to the remaining crystal. Now we have to consider another effect: The tea (or any solvent for that matter) can only accommodate a certain amount of molecules being dissolved in it (in our case the sugar). When the limit is reached there is no space (simply put) for any more sugar molecules left. Stirring removes the sugar molecules next to the remaining sugar crystal by distributing them in the rest of the tea, so that now there is new space for additional sugar molecules to exit from the crystal into the tea. Without stirring, the sugar molecules also get distributed through your whole cup of tea, by a process called diffusion, but this is much slower than simply stirring the tea.
To increase the rate of solution of a solid in water what do you do?
The process of dissolving is and can be aided by stirring, swirling, or shaking. However there are other factors which can determine the rate a solute dissolves in a solvent. One such factor is temperature. Example: sugar dissolves faster in hot tea rather than in cold..
Does the temperature of water make a difference to the time that sugar dissolves?
Yes, the hotter it is, the faster it dissolves the sugar. it is also faster the smaller the sugar is.
What happens to sugar when it is put into cold water and not stirred?
The sugar dissolves ... slower than it would if the water were warm, andmuch slower than it would if you stirred.If there's more sugar than that amount of water can hold at that temperature,then the sugar stops dissolving at some point, and won't dissolve any moreeven if you start stirring. That's the point of saturation at that temperature.
What dissolves faster in room temperature water salt or sugar or a laundry detergent?
Sugar
Why Rizal considered his fasther as model father?
The sugar cubes soften when placed in the water and begin to dissolve. The sugar cube in the hot water dissolves the fastest. Sugar will dissolve faster when you stir the solution quickly because the act of stirring increases kinetic energy which increases the temperature.
Why when you stir sugar dissolves?
When sugar is in water only so much can be dissolved when the maximum amount of sugar is dissolved the water become saturated. When the sugar is placed in the water the water immediately surrounding the sugar dissolves some of it and becomes saturated. Stirring brings unsaturated water into contact with the sugar which can then dissolve more of the sugar.
Does temperature affect the amount of sugar that dissolves in water?
Sugar that is dissolved in hot water, dissolves faster than sugar dissolved in cold water.

Crushing the sugar cube allows more surface area with the water that hydrates (dissolves) the sugar molecules. Therefore, it will dissolve faster. Stirring helps.
How many teaspoons of sugar dissolves in a cup of water at room temperature water?
None. Sugar goes into solution. Salt dissolves separating into Na and Cl attached to Water.

The temperature of the solvent (water) plays a role because the higher the temperature the more motion in the volume at the molecular level.
How long does it take for sugar to dissolve in lukewarm water?
This depends on: - mass of sugar - granulation of sugar - volume of water - stirring (and intensity of stirring, stirrer type) - type and geometry of the beaker - exact temperature of water
