O degrees Celsius or less ;)
0 degrees Celsius
They melt because the heat in the air is warmer than the temperature of the ice cubes.
If Ice cubes are melting in water, the temperature of both the ice cubes and the water will be exactly the freezing temperature of water: 32F, 0C. You cannot change this. You can add heat to make the ice cubes melt faster, but the extra heat will have no effect on the temperature, It will all go to melting the ice cubes.

Water has a higher temperature in ice causing it to melt faster.
The ice cube will melt faster if it was previously dunked in water. Ice cubes will melt when they are placed in liquid since water temperature is higher than that of ice.
it would depend on the temperature of the room. at 21*c it would melt in 15minutes
place ice cubes in water or air at a warmer temperature than 32 Deg.F. place ice cubes in water or air at a warmer temperature than 32 Deg.F.
The answer depends on how large the ice cubes are, what temperature they are at the start, the ambient temperature, whether or nor the melt water is allowed to drain away or not, and so on. Without information on these factors it is not possible to answer the question.
At room temperature an ice cube...is rapidly melt. It is impossible for the ice to have the room temperature (ca. 20 0C) at normal pressure.
the temperature of ice cubes are lower than the temperature of the water around them. The heat energy from the water is used up in the process of melting the ice, so the water temperature drops.

Yes ice cubes can be referred as renewable sources of energy. When subjected to high temperatures they usually melt. They can subsequently turn into ice when the temperature is lowered below 0 degrees.
