Water does not commonly form a gas, but rather a vapor which is slightly different (but really just the name of a gas that is normally a liquid). - There is latent heat in water so you can remove energy without changing the temperature of the water (only exactly at a phase change though).
The â¦ opposite also occurs: heat is transferred from a substance during a phase change without a decrease in temperature as intermolecular bonds form.emperature can be used to recognize a phase change because during  the phase change the temperature of the substance does not change. Edit. Share to: 1  A Basic Phase Change Definition Scientists often are very interested in the chemical makeup of matter, but they are also interested in the physical makeup of substances.
