Physics is an amazing science that can explain all the processes taking place on our planet. However, new knowledge is not always easy to understand. For this reason, we will answer one of the important questions that interest many people in this article. Why are gases heated by compression?
Molecular physics
To answer this question, we should turn to molecular physics, since in this case the temperature changes due to changes in the motion of the molecules of a substance in a gaseous state. Explaining why gases are heated during compression, we pay attention to the piston or other object with which compression occurs. In this process, many elastic shocks occur. The volume of gas decreases, which means that the distance between the molecules of the substance decreases. These particles begin to collide with each other more often, due to which there is a strong jump in the increase in energy produced by them, which is the main reason why gases are heated during compression.
Molecular kinetic theory
The ideal model that the theory implies becomes an ideal gas. In the ideal gas model under consideration, the particles look like absolutely elastic balls in contact with each other and with the surface of the vessel exclusively during collisions. The total particle volume is quite small in comparison with the volume of the vessel itself. Such a gas perfectly represents the interaction of existing gases. The main problem considered by this theory is the establishment of a relationship between various parameters of a substance.
The relationship of temperature and kinetic energy
As you remember from the lessons of physics already completed, kinetic energy is directly related to temperature. Temperature is a measure of kinetic energy for particles in the process of thermal motion. Thus, the gas is heated, and we gave a detailed answer why the gases are heated during compression.
Conclusion
Let's hope that this article turned out to be useful to you, and you were also interested in reading it and getting new knowledge from one of the sections of this science, that is, molecular physics. Now, without a doubt, you can explain to another person why the gases are heated by compression. Good luck in your further study and knowledge of the world around us, because this is a very interesting and fascinating activity. Never stop, despite possible difficulties that may get in your way.
