In ice, each molecule of water is hydrogen bonded to four other water molecules, forming a hexagonal crystal lattice. This structure causes the ice to increase in volume and become less dense when it freezes.
water gives up energy to make ice
supercooled water freezes around ice nucleus or water vapor changes to ice crystals
The process by which water vapor changes to a solid is called deposition. This occurs when water vapor in the air changes directly into ice without passing through the liquid phase. This can happen when the temperature and pressure are low enough for the water vapor to bypass the liquid phase and form ice crystals.
Water changes into ice by solidification, aka freezing. When water changes into ice, the liquid particles are reorganizing themselves to become a solid particle.
If the bowl of ice and water is kept at exactly zero degrees Celsius, the ice will remain in equilibrium with the liquid water. The ice might slowly melt into water, but at the same rate it will refreeze into ice due to the balance between freezing and melting processes at this temperature.
The process when snow or ice changes to water is called melting.
Ice forms from the freezing of water.
When water is cold, it changes into ice, which is the solid form of water.
Melts
ice to water to ice
When water vapor condenses, it changes from a gas to a liquid by losing heat energy. This process forms water droplets or ice crystals, depending on the temperature. Condensation is the reverse of evaporation, where water changes from a liquid to a gas.
The ice melts and the water gets cooler.
