Higher temperature increases the speed of dissolving.

Reason: raising temperature increases molecular kinetic energy, so solvent and solute molecules move and collide more, diffusion is faster, and the solute dissolves more quickly. (Note: for gases, higher temperature usually reduces solubility but can still increase the rate at which gas leaves solution.)
