Does hot water melt cold things faster than cold water?
Of course. When something is hotter than something else, it means it has more energy, which also means it's particles are moving more. The particles of the water will bump into whatever your trying to melt and give it some of the particle's energy, which hopefully will be enough make it become a liquid as well. The hotter the water the more energy it has, and the more quickly it can melt "things".
