Dissolve Definition:

In chemistry, to dissolve is to cause a solute to pass into solution. Typically, this involves a solid going into liquid phase, but dissolution can involve different phases.

Dissolve Examples:

Stirring sugar into water is an example of dissolving. The sugar is the solute, while the water is the solvent.

Releasing the helium inside a balloon to the atmosphere is also an example of dissolving.

The helium gas dissolves in the larger volume of air.
