Yes
The ice will begin to melt as the surrounding water transfers heat to the ice, causing it to raise in temperature until it reaches its melting point. Once the ice reaches this point, it will start to melt and change from a solid to a liquid.
Any hot liquid melt ice.
almost any liquid can melt ice as long as its warmer that the ice
No, or else it would not be made as a cup.

put it in a microwave oven
More surface contact with air.
keep it in liquid ammonia
It obsorbs liquid.
Ice and butter both melt into a liquid.
