How does phase change in water help organisms in environment?
The processes of melting, evaporation, and sublimation absorb energy. This added energy causes the molecules to change their bonding pattern. In the Earth system, this energy must be supplied by the surrounding environment. Thus, these phase changes result in cooling of the surrounding environment.
