The temperature of the water and the temperature of the air would have to be factors in the answer.
EDIT:
Assuming the air and water are the same temperature, it would melt much faster in water. The thermal conduction is much higher.
Ice cubes don't faster in cold water because the temparature of cold water is low, ice cubes melt faster in high temparature.
water
because water heats up faster
Water has a higher temperature in ice causing it to melt faster.
yes
Ice cubes will melt faster in darker colour water than lighter colour water
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.
Because water is a part of an ice cube
in your hand because of your body heat
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.
because atoms in hot water vibrate faster, and cold water vibrates slower, hence movement generates heat, heat speeds up the ice cube's atoms, as the ice cube's atoms speed up it begins to expand, spread out it's mass and melt.
The rate at which ice cubes melt in water depends on factors such as the temperature of the water, the size and shape of the ice cubes, and the amount of agitation in the water. Generally, smaller ice cubes will melt faster than larger ones due to their increased surface area exposed to the water. Warmer water will also cause ice cubes to melt more quickly compared to colder water.
