heat, of course!
The heat from the hot water is transferred to the ice, making the ice heat faster, thus causing it to return to room temperature faster, making it melt faster.
Assuming they are the same temperature, the ice will melt faster in water, due to water's high specific heat.
The melting rate of an ice depends on the temperature of the surrounding. If the temperature is higher in the surrounding then the ice will melt at a faster rate and if the temperature is low then it will take more time to melt. The process of heat exchange is important whether it is air or water.
Cold water will not melt the ice cube in record time, but hot water will, but salt water will also melt it fast, but if you add both together the ice cube will melt alot fast. Deceasing time alot.
No heat so it cant melt like the warm water. they are the same temp/.
Water doesn't melt, it vaporizes and becomes a gas. The energy from heat melts or vaporizes all matter.
Assuming that the air and water in your question have the same temperature, ice would melt faster in the water, as there is a greater degree of heat transferance in water due to its greater density.
an ice cube melts faster in water.it depends on the temperature of the air or water, if the water is warmer than the room air temperature, it will melt faster in the water.
in your hand because of your body heat
sunlight will
same speed but heat may speed a little bit
it would melt faster in a glass container faster.
