When ice is melting is it releasing heat or absorbing heat?

e, energy must be added to cause the ice to go from a higher state to a lower ordered state. When ice melts or water evaporates, energy must be taken from the environment in order for the ice or liquid to move to a less ordered state. Energy is needed to weaken the individual hydrogen bonds between H20 molecules. When water (in any of the three phrases) moves from a higher to a lower ordered state, the air surrounding the H20 will have heat subtracted from it. The three processes that subtract heat from the surrounding air are evaporation, melting and sublimation (solid to gas). When water (in any of the three phrases) moves from a lower to a higher ordered state, the air surrounding the H20 will have energy added to it. This is called a release of latent heat (e.g. when heat is subtracted from liquid water, the individual water molecules will slow down. They eventually slow down to the point at which the hydrogen bonds do not allow the liquid to rotate anymore. Ice now develops. The energy the water molecules once had to rotate has been given up to the surrounding air). The three processes that add heat to the surrounding air are condensation, freezing and deposition (gas to solid).

absorbing heat because it would be releasing cold not heat every thought about leaving ice cubes in a cup on the table and they suddenly melt, its because the heat it getting trapped in the cup either way so it would be no escape so it goes into the ice to melt.

It is absorbing heat. The reaction goes from solid to liquid and in order to break the solid bonds you need energy, so it absorbs the energy needed to break the bonds which allow it to transform into a liquid.
