Because the molecules, of the solute and the solvent, have more energy, and therefore move around more quickly. This means the substances can disburse (mix) more quickly.
Hot water does not dissolve. Neither does "cold". And, the grammatically correct question would be "Hot does hot water dissolve faster than cooler water."
