dG = dH -TdS
Gibbs free energy has to be negative, ie. Temperature*Entropy has to be greater than enthalpy.
First the crystal lattice has to be broken which costs energy, but then energy is gained when water and sugar interacts.

The sucrose has hydroxyl groups that have a slight negative charge. The positive charge of the oxygen found in the water molecule binds with the sugar. As the hydration shell forms around the sucrose molecule, the molecule is shielded from other sugar molecules so the sugar crystal does not reform. - smart persons answer

What mixtures can dissolve?
Sugar can dissolve in water.
How fast does sugar dissolve in water and how fast salt dissolve in water?
The amount of time and speed it takes to dissolve sugar in water and dissolve salt in water depends on the amounts of salt and sugar, the amount of water, and the temperature of the water. The approximate time needed to dissolve the sugar and salt in water is 25 minutes.
Why does a sugar cube dissolve slower when not stirred?
As you are not agitating and breaking away the sugar crystals, the outer layers have to dissolve before the inner layers can, causing the sugar to take longer to dissolve.
Can water dissolve more sugar or salt?
More sugar can dissolve in water than salt.
Why do lumps of sugar dissolve slower than grains of sugar?
Because the particles mix together first and get bigger then it dissolve.
Why does a sugar cube dissolve in warm water?
In warm water the forces between sugar molecules are weakened.
What do you mean by solubility of solute in solvent?
the nature of the solte and solvent determines the attractive forces that exist between particles in solution
What mixtures can dissolve?
Sugar can dissolve in water.
Which will dissolve faster in liquids salt or sugar?
Sugar should dissolve faster in a liquid.
How does a grain of sugar dissolve in water?
the sugar will dissolve in water.
What is the maximum amount of sugar that will dissolve in 100ml water?
204g of sugar is the maximum amount of sugar that will dissolve into 100mL of water.
How fast does sugar dissolve in water and how fast salt dissolve in water?
The amount of time and speed it takes to dissolve sugar in water and dissolve salt in water depends on the amounts of salt and sugar, the amount of water, and the temperature of the water. The approximate time needed to dissolve the sugar and salt in water is 25 minutes.
Why does a sugar cube dissolve slower when not stirred?
As you are not agitating and breaking away the sugar crystals, the outer layers have to dissolve before the inner layers can, causing the sugar to take longer to dissolve.
How do you dissolve water and sugar?
by heating the water slowly and by stirring using a spoon, you can dissolve salt and sugar.
Is a solvent liquid that dissolves sugar?
No, a solvent can dissolve many things and not necessarily just sugar. Water is a solvent and also a liquid and can dissolve sugar, However, it can also dissolve many other things.
Does sugar dissolve?
yes
Can sugar dissolve in isopropanol?
no
