Does ice melt faster in water or air?

joker asked the Naked Scientists:
   
Does ice melt faster in water or by itself?

What do you think?

In water because heat conduction is more efficient, anyway it depends on the conditions: air and water temperature, if they are initially stationary or not, how convection currents are allowed to flow, on the shape and dimensions of the block/blocks of ice, ecc.

I agree water is a great conductor of thermal dynamics.
Ice will melt faster in water until the water become as cold as the ice. Providing the mass of the ice and the volume of water it is cooling.

I was wondering what the third condition is "or by itself"

Water, It conducts heat 20 times faster than air, that's why jumping into a lake that's 2C feels a lot colder than air that's 2C its also why air pockets are used in wall cavities and your loft as insulation,

Water, cause in  water heat conduction is more than ice.
