Boiling water is an event we see or take part in every day\u2014be it to make coffee or cook or simply make water potable. We don\u2019t think too much about boiling water when we do it.<\/p>\n\n\n\n
But what is this process of boiling? Let\u2019s recall what we learned in school about it. Boiling is defined as a process of heating a liquid up to a temperature where the liquid converts into vapor.<\/p>\n\n\n\n
The temperature at which a liquid turns into vapor is called its boiling point. It is the temperature where the atmospheric pressure is equal to the vapor pressure of the liquid.<\/p>\n\n\n\n
In the process of boiling, not just a few molecules at the surface, but all the molecules in the liquid take place, making it a bulk phenomenon.<\/p>\n\n\n\n
The normal boiling point of water is 211.94 degrees Fahrenheit and the standard boiling point of water is 211.29 degrees Fahrenheit. (Normal temperature = boiling temperature at 1 atm; Standard temperature = boiling temperature at 1 bar)<\/p>\n\n\n\n
In this article, we will look at boiling water and understand if it is a physical change or a chemical change. But before we classify boiling water under either of the categories, we need to understand what a physical change and chemical change is.<\/p>\n\n\n\n
