What makes ice to melt faster?
Answer 1:

Add pressure! It will make ice melt faster; or put salt on ice--this effectively raises the freezing temperature. Because the ice is below that temperature, it will melt.

Answer 2:

Ice is converted into water by the addition of energy - in the form of heat.The amount of heat energy needed to convert a solid to a liquid depends on the 'heat of fusion' of that substance. In the case of water, the heat of fusion is 79.72 calories per gram.

To make ice melt faster, this heat energy must be added faster. For instance, a room at 2 degrees Celsius will melt ice, but slowly. On the other hand, a room at 40 degrees Celsius will melt the ice much faster because there is more heat energy available in the room. If you point a hair dryer at the ice, it will melt even faster because you're forcing heat into it with the hot air.
