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

      Change<\/strong><\/h2>\n\n\n\n

      Change is a constant part of life. It is happening around us at all times. Chemists often deal with different changes more actively in their work. The changes that a matter can undergo tell a lot about the nature of the matter.<\/p>\n\n\n\n

      Chemists have classified changes that they observe into two categories\u2014physical change and chemical change.<\/p>\n\n\n\n

      What Is a Physical Change?<\/strong><\/h3>\n\n\n\n

      Chemists classify changes in which no bonds are formed or broken as physical change. This implies that the compounds in the change remain the same even after the change and no new material is formed.<\/p>\n\n\n\n

      The properties of the materials involved<\/a> in a physical change stay the same even after the physical change. The properties here include color, boiling point, etc.<\/p>\n\n\n\n

      A physical change involves the movement of the molecules and not a change in the nature of the molecules. Some typical physical changes include:<\/p>\n\n\n\n
