You've got it in reverse. When sucrose dissolves in water, sucrose is the solute, and water is the solvent. In order to dissolve, sucrose molecules have to be more attracted to water molecules than they are to other sucrose molecules. If the attraction of sucrose to sucrose was greater than the attraction of sucrose to water, then there would be no reason for the solid sucrose to turn into the aqueous sucrose solution. Sucrose molecules would simply remain firmly attached to each other if that were the case.

It is a decrease.
the higher the temperature, the more contact there is to the object to make the solvent mix with the salute to make the sucrose.

At room temperature, the greatest attractive forces exist between particles of
salt

Attractive forces pull particles together.

The particles hardly are affected by the attractive forces
the higher the temperature, the more contact there is to the object to make the solvent mix with the salute to make the sucrose.
The particles in the solid (solute) break apart and form links with the particles in the liquid (solvent). There are strong forces of attraction between the molecules and particles inside the solute. These forces keep the particles together and make the solute a solid because they attract the solute particles tightly together. There are also strong forces of attraction between the molecules and particles inside the solvent. These forces keep the particles together and make the solvent a liquid because they attract the solvent particles slightly together. There is also an attractive force between the solute and solvent particles. To break these forces and from a bond between the solute and solvent particles energy is needed. This energy is gained from heat (the process of dissolving is speeded up through heat.) In conclusion, the particles in a solute break apart of their attractive forces and form bonds with the solvent particles through the attraction between the solute and solvent particles and through the energy gained by heat.
Particles are small, hard spheres of insignificant volume. Attractive and repulsive forces between particles are weak.
