What physical property does sugar have that makes it dissolve in water?

Answer 1

A grain of sugar is actually a large collection of sugar molecules (with most of the water eliminated if dry). When the sugar grain is placed in water the sugar molecules are free to separate and drift in the water (without a chemical change to the molecules). Drying the water out again restores the sugar to crystal grains although perhaps much larger. For sugar to dissolve, water must wet it (unlike wax and oils, etc.).

Answer 2

in chemistry, the general rule is "like disolves like." chemicals can basically be divided into two catagories, polar and non-polar which is based on dipole moments in a molecule resulting from differences in electronegativity.

but the simple answer is that sugar is a polar molecule like water so the two will dissolve into each other.

Answer 3

Sugar is a polar molecule, meaning it has both a positively and negatively charged end. Water is also a polar molecule. This property allows sugar to form hydrogen bonds with water molecules, causing it to dissolve easily in water.
