Chemistry question: Does an ice cube melt faster in water than in air? I think it all depends. What is the ambient temperature of the air or water and what kind of water (moving water or settled, salt ... Does ice melt faster in the air? Does ice melt fast in water or air? Does ice melt faster on air or water?

Ask the experts your physics and astronomy questions, read answer archive, and more. ... The air and water may have particles moving the same speeds, but the water has more heat because there are more particles. Picture it this way. The ice melts as fast moving particles slam into the slow moving ice particles.

Ice melts because it has gained energy from its surroundings and made the transition from a solid to a liquid, just as water in a kettle gains energy and goes from a liquid to a gas as it boils. In the case of the melting ice, the energy is gained from either the water it's in or the air around it.

Let us assume a room temperature of 22C. For an object sitting in air without a fan or other forced convection, ... As the ice melts, the water drips away so we will assume that all of the heat goes to melt the ice. The heat of fusion (the amount of heat necessary to transform ice to water) is 80 cal/gram or 333 joules/gram.

When the molecules vibrate too fast, the ice melts. When the molcules in water vibrate much too fast the water boils. If you think that boiling water is very hot, take a holiday on the sun; ... Light is refracted when it passes from one material into another, i.e. out of the air and into water or in and out of glass.

Melting Ice in Water or Air ... This is because water is better at transferring heat to the ice cube than air is. You can try this experiment yourself. By making the air hot and the water cold, you could also arrange for the ice cube in air to melt first.
