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.

What happen when you stir water and sugar together?
When you stir water and sugar together, the sugar dissolves in the water to create a solution. The stirring action helps break down the sugar crystals, allowing them to mix more easily with the water. This results in a sweetened water mixture where the sugar particles are evenly dispersed throughout the water.
Does temperature affect the amount of sugar that dissolves in water?
Yes, temperature does affect the solubility of sugar in water. Generally, sugar dissolves more easily in hot water than in cold water because the increased kinetic energy at higher temperatures helps to break down the bonds between sugar molecules.
Which is affected most by increasing the temperature of the waterhow fast salt dissolves or how fast sugar dissolves?
Sugar dissolves faster in warmer water compared to salt. This is because increasing the water temperature provides more energy to break apart the sugar molecules, allowing them to dissolve more quickly. Salt, on the other hand, already dissolves relatively fast in water regardless of temperature, but it tends to dissolve slightly faster in warmer water as well.
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.
Is stirring sugar into a cup of tea a physical or chemical change?
It is a chemical change. Table Sugar is the crystallized form of liquid Sucrose(also simply known as, Sugar.) By stirring sugar into the tea you are using the tea as a catalyst in that it "hydrates" the crystal and causes it's chemical structure to return to the liquid form and be absorbed into the makeup of 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..
How fast does sugar dissolve in water?
The speed at which sugar dissolves in water depends on various factors such as temperature, stirring and the presence of impurities. Generally, sugar dissolves faster in hot water compared to cold water due to increased molecular motion at higher temperatures.
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 factors influence the speed rate which the sugar dissolves?
Factors that influence the speed at which sugar dissolves include temperature (higher temperatures dissolve sugar faster), agitation (stirring or shaking speeds up dissolution), particle size (smaller sugar crystals dissolve faster), and the surface area of sugar exposed to the solvent (greater surface area increases dissolution rate).
What dissolves faster sugar left alone in water or sugar stirred in the water?
Sugar stirred in water dissolves faster than sugar left alone in water. By stirring the sugar, it increases the surface area of the sugar particles coming into contact with the water, speeding up the dissolving process.
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.
What dissolves faster in room temperature water salt or sugar or a laundry detergent?
Sugar
How do you dissolve rock sugar in water?
To dissolve rock sugar in water, first crush the sugar into smaller pieces to speed up the dissolving process. Then, heat the water to a higher temperature (near boiling) and stir the sugar in until it completely dissolves. Alternatively, you can let the sugar sit in cold water for some time, stirring occasionally until it dissolves.
What happen when you stir water and sugar together?
When you stir water and sugar together, the sugar dissolves in the water to create a solution. The stirring action helps break down the sugar crystals, allowing them to mix more easily with the water. This results in a sweetened water mixture where the sugar particles are evenly dispersed throughout the water.
Does temperature affect the amount of sugar that dissolves in water?
Yes, temperature does affect the solubility of sugar in water. Generally, sugar dissolves more easily in hot water than in cold water because the increased kinetic energy at higher temperatures helps to break down the bonds between sugar molecules.
What dissolves faster in heated water sugar or salt?
Sugar typically dissolves faster in heated water compared to salt. This is because sugar molecules are smaller and more readily break apart in hot water, facilitating a quicker dissolving process. Salt, on the other hand, requires a bit more time and stirring to fully dissolve even in heated water.
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.
