Liquid water evaporates at all temperatures, so puddles disappear because they evaporate. The evaporation is somewhat faster with higher temperatures and slower with lower temperatures. Evaporation happens from the open surface of water. The larger the surface, the faster the evaporation. For this reason a puddle evaporates faster than the same volume of water in a glass. Boiling, however, happens throughout the entire volume of water at the same time, and is therefore much faster than simple evaporation.
