When solid ice gains heat, it changes state from solid ice to liquid water in a process called melting Ice cubes in a cold drink, for example, gradually melt Each

Water has a high specific heat index It takes much more heat to raise the temperature of a volume of water than the same volume of air This is why water is used as a coolant This property of water is a major determinant of global climates and rates of global climate change - changes in temperatures are gradual - “lake” effects
All phases that share phase boundaries with liquid water (ices Ih III V and VI and VII) have disordered hydrogen bonding The phases with ordered hydrogen bonding are found at lower temperatures and are indicated in light blue below The structural transformation conditions of some of these ices during compression have been described [1795]

What are the three phases of water?
Students learn that water has three phases: solid, liquid and vapor. But there is something more: in our laboratory at the University of Washington we have uncovered a fourth phase.1 This phase occurs next to water loving (hydrophilic) surfaces.
What is the fourth phase of water?
Taking into account this fourth phase allows many of water’s “anoma-lies” to vanish: those anomalies turn into predictable features. Water becomes more understandable, and so do entities made largely of water, such as oceans, clouds, and human beings.6 The insights described here arose out of a departure from the mainstream science route.
What is the difference between phase change and condensation?
Phase Changes Molecules in a liquid are in constant motion; some moving faster, others slower. Those molecules with enough kinetic energy escape from the liquid surface, i.e. vaporize. Condensation: When molecules in the gas phase collide with the liquid surface, they loose energy and return to the liquid.
