How physics define cooling and natural way of cooling

        This article is By Rhett allen Refrigeration: the process of decreasing the temperature of some thing (my definition). Air conditioning (AC) can be a form of refrigeration. There are several ways to reduce the temperature of things – like a person or a beer. The history and physics of cooling things can be quite interesting. I’m not a historian, so I am only going to speculate on the timeline of events in the life of refrigeration. However, I feel comfortable explaining the physics in each method. Humans Discover Sweat Humans just can’t help it. Sometimes they get hot. But alas! Humans have a built in cooling systems. It’s called sweat. In order to understand how it works, maybe we should first look at temperature. You can measure the temperature in Celsius (°C) or Fahrenheit (°F), but what are you actually measuring? If I were to give a simple definition of temperature, I would say that it is a measure of the average motion energy of the particles that make up that object. T…
