What happens to boiling water if you increase temperature?

evaporation This is the chemical reaction for water heating: H2O (liquid) + heat ---> H20 (gas) This is an endothermic reaction, meaning that by adding heat, it will shift the reaction towards the products, thus making more H2O gas. It is simply a phase change.

Is H2O solid or liquid?

H2O is commonly found in three states of matter: solid, liquid, and as a gas. When H2O is cooled below 32 degrees Fahrenheit, under normal atmospheric pressure, it becomes a solid (Ice). Between 32 and 212 degrees Fahrenheit, it will be found as a liquid (Water). Finally, when H2O is heated above 212 degrees Fahrenheit, and under normal atmospheric pressure, it will become a gas (Water Vapor, commonly referred to as Steam). In conclusion, H2O is both a solid, a liquid, and a gas, depending on what temperature and pressure it is under.


What allows liquid water to exist?

Liquid water exists based on the molecular structure of the water, and the temperature of those molecules. Liquid water is water, H2O within a temperature range of 0-100 degrees celsius. The H20 compounds cling to other H20 compounds due to gravity, and a large amount of H2O compound form molecules of water.
