Why does dry ice melt faster in hot water than cold water?

Answer 1

When Ice melts, it does so using latent heat. In other words as you heat the Ice/water mixture, until all the Ice has melted the temperature of the mixture does not increase until all the Ice has gone. The energy goes into melting the Ice and this is called the latent energy.

Thus if you add the same sized ice cube to same size classes of water but one of the glasses is filled with hot water, the ice in the hot water will melt faster because the heat of the water will be used for the latent heat of melting.

Answer 2

Dry ice sublimes directly from a solid to a gas when exposed to warmer temperatures. In hot water, the increased temperature causes the dry ice to sublime more rapidly compared to in cold water. This results in faster melting or disappearance of the dry ice in hot water compared to cold water.

Answer 3

ice melts faster in hot water because the hot water is transfering the separate particles in hot

Answer 4

Ice melt faster in a warmer temperature because the molecules in ice move more freely in a warmer temperature allowing it to melt faster.

Answer 5

Dry ice is cold, so it melts faster in higher temperatures.
