The physical world surrounds us everywhere. His laws underlie everything that we can see and feel. The purpose of this article is to reveal the topic of thermal phenomena and formulas of thermal processes, to explain their application using the example of modern technologies.
Such great scientists as Isaac Newton, Robert Hook, Robert Boyle, Daniel Bernoulli studied this phenomenon . Already in those days, scientists knew that the world consists of atoms, which were then called "corpuscles", which meant particles. And the theory of thermal phenomena, in turn, was called corpuscular.
The great scientist Mikhail Vasilievich Lomonosov made a considerable contribution to science by studying thermal phenomena. Considering heat as the rotational movements of atoms, he was able to explain such complex physical processes as the melting of metals, the evaporation of liquids, the thermal conductivity of bodies, and also opened the world to the greatest degree of cold.
The concept of thermal phenomena in physics and the formulas of thermal processes
Without understating, we can say that thermal phenomena are an important component in nature. This is all that is associated with a change in the temperature of physical bodies. The study of these processes is carried out by molecular physics and thermodynamics, using the methods of statistics and kinetics observe the motion of atoms. In nature, this can be seen when ice melts, water boils, metal melts, the sun shines, and other similar processes occur.
It is known that all bodies are composed of molecules that randomly move inside matter. When heated, the molecular velocity increases, and when cooled, decreases. This movement itself is endowed with kinetic energy, which is released when the temperature changes. This phenomenon is called heat transfer.
When we drop a cold spoon in a cup of hot tea, where the temperature is 100 ° C, the spoon gradually heats up, and the tea cools a little. This is the simplest example of heat transfer that we can observe in everyday life.
In physics, there are formulas of thermal phenomena. With their help, the absolute temperature of the substance is calculated according to Kelvin, the amount of heat, evaporation and heat temperature, fuel combustion and heat of fusion. Also, the temperature on the Fahrenheit scale can be converted into an indicator on the Celsius scale using physical formulas.
Scopes of the thermal phenomenon
The laws of thermodynamics are widely used in aviation, in the design of the heating system of houses, in steam engines and internal combustion, jet turbines. They are used for melting various metals, in industry, to create heat-resistant materials and other things (up to the space industry).
Based on this simple phenomenon that we find everywhere in the world around us, an incredible number of mechanisms have been invented. To this day, we use these inventions in everyday life. This is how an electric kettle and a refrigerator work. Even the fact that a person is warming under a blanket is also an example of a thermal phenomenon.
