Answer:

1.decreasing

2.increasing

3.sugar because faster to dissolve in water while flour is the insoluble one.

4.The effective means of increasing the dissolving rate of sugar in water is by stirring or agitating the solution. The stirring allows fresh solvent molecules to continually be in contact with the solute. Hot water dissolves faster than cold water.

5.water,Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules.

To some extent, Sugar does not dissolve very well in alcohol because alcohol has a large part that is pretty non-polar. Sugar hardly dissolves at all in oil because oil is very non-polar.
