Boiling point


The boiling point is the term given to the process that occurs when a matter changes state from liquid to gas. It also refers to the temperature that causes the vapor pressure of a liquid to equal the vapor pressure through boiling.

In a simple way, the boiling point refers to the temperature at which a liquid boils, which is linked to the properties of the liquid and not to its quantity. It should be noted that once the liquid has boiled and is boiling, the temperature does not undergo any variation, that is, it is constant.

The variation in temperature is related to the kinetic energy of its molecules. Normally, there are few molecules that break the surface tension, but once the boiling point temperature is reached, the entropy increases and the particles present become disordered.

A clear and simple example is that of water, its boiling point is one hundred degrees Celsius. In other words, you can put the water at room temperature, which is 20 degrees, in a container and take the container to the fire. The water, at that moment, will be in a liquid state. But as the temperature increases, the surface tension will begin to change, until reaching a hundred degrees, the water will reach its boiling point and begin to boil, passing into a gaseous state. It is important to note that it does not matter if the vessel contains half a liter, one liter or three liters of water, the boiling point will always be one hundred degrees.

In some parts of the world, where poverty reigns, there are diseases such as cholera, which is present in the water and what has been sought is to educate the community on issues related to hygiene and food handling. Since water is one of the key elements in the spread of the Vibrio Cholerae bacteria, which is the cause of cholera. It is important to note that if you want to wash food, drink it or use it for cooking, it is always recommended to boil it beforehand to kill bacteria.
