Take Boyle`s Law, one of the gas laws that govern how temperature, volume, and pressure affect gases. Boyle`s law, named after Robert Boyle, the 17th-century scientist who first published about it, is a description of the relationship between the pressure and volume of gas in a container (assuming the temperature remains constant). Your eyes may have become glassy, but you already know everything about Boyle`s Law, and that`s why you need physics lessons to give a name to what you already figured out when you burst your first balloon. Sometimes science is just a way to make connections between what you know and what we know together. At some point in your life, you`ve probably taken a physics class – or will attend at some point. This is for your own good, although it is possible that you are not feeling the truth at this time. One of the reasons why the physics course is valuable is related to adding a name and image to things you already know. A fixed amount of a gas occupies a volume of 1L and exerts a pressure of 400 kPa on the walls of its container. What would be the pressure exerted by the gas when it is completely transferred to a new container with a volume of 3 liters (assuming that the temperature and amount of gas remain constant)? Boyle`s law, also known as Mariotte`s law, is a relationship about the compression and expansion of a gas at a constant temperature. This empirical relationship, formulated in 1662 by the physicist Robert Boyle, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; that is, in the form of an equation, PV = k, a constant. The relationship was also discovered by the French physicist Edme Mariotte (1676). Boyle`s Law, Charles` Law and Gay-Lussac`s Law form the Combined Gas Act.
The three laws of gas in combination with Avogadro`s law can be generalized by the law of ideal gas. Thus, when the volume is reduced by half, the pressure is doubled; And when the volume is doubled, the pressure is reduced by half. Therefore, the gas exerts a pressure of 133.33 kPa on the walls of the 3-liter container. In practice, this means that when the volume of the gas decreases, the pressure must increase and vice versa. P is the pressure exerted by the gas and V is the volume occupied by it. This proportionality can be converted into an equation by adding a constant k. This equation can be used to predict the increase in the pressure exerted by a gas on the walls of its container when the volume of its container is reduced (and its absolute quantity and temperature remain unchanged). (name) The observation that the pressure of an ideal gas is inversely proportional to its volume at constant temperature.
According to Boyle`s law, any change in the volume occupied by a gas (at a constant quantity and temperature) results in a change in the pressure exerted by it. In other words, the product of the initial pressure and volume of a gas is equal to the product of its final pressure and final volume (at constant temperature and number of moles). This law can be expressed mathematically as follows: A gas exerts a pressure of 3 kPa on the walls of container 1. When container 1 is emptied into a 10-litre container, the pressure exerted by the gas increases to 6 kPa. Look for the volume of the container 1. Suppose that the temperature and the amount of gas remain constant. This law was the first physical law to be expressed as an equation describing the dependence of two variable quantities. . This relationship between print and volume was first established in the 17th century by Richard Towneley and Henry Power.   Robert Boyle confirmed their discovery through experiments and published the results.  According to Robert Gunther and other authorities, it was Boyle`s assistant, Robert Hooke, who built the experimental device.
Boyle`s law is based on experiments with air, which he saw as a liquid of particles resting between small, invisible sources. At the time, air was still considered one of the four elements, but Boyle disagreed. Boyle`s interest was probably to understand air as an essential part of life;  For example, he has published work on the growth of airless plants.  Boyle used a closed J-shaped pipe and after pouring mercury on one side, he forced the air on the other side to contract under the pressure of mercury. After repeating the experiment several times and using different amounts of mercury, he found that the pressure of a gas under controlled conditions is inversely proportional to the volume it occupies.  The French physicist Edme Mariotte (1620-1684) discovered the same law independently of Boyle in 1679, but Boyle had already published it in 1662.  However, Mariotte found that the volume of air changes with temperature.  Therefore, this law is sometimes referred to as Mariotte`s law or Boyle-Mariotte`s law. Later, in 1687 in the Philosophiæ Naturalis Principia Mathematica, Newton mathematically showed that in an elastic liquid consisting of dormant particles between which are repulsive forces inversely proportional to their distance, the density would be directly proportional to the pressure, but this mathematical treatise is not the physical explanation of the observed relationship. Instead of a static theory, a kinetic theory is needed, which was provided two centuries later by Maxwell and Boltzmann. This expression can be derived from the pressure-volume relationship proposed by Boyle`s law. For a fixed amount of gas maintained at a constant temperature, PV = k.
Therefore, Boyle`s law, also known as Boyle-Mariotte`s law or Mariotte`s law (especially in France), is an experimental law of gas that describes how the pressure of a gas tends to decrease as the volume of the container increases. A modern statement of Boyle`s law is that Boyle`s law is often used as part of an explanation of how the respiratory system works in the human body. This often includes explaining how lung volume can be increased or decreased, thereby causing a relatively lower or higher air pressure in them (in accordance with Boyle`s law). This forms a pressure difference between the air in the lungs and the pressure of the ambient air, which in turn fails to inhale or exhale when the air passes from high to low pressure.  Robert Boyle was interested in the concept of race, believing that skin color was inherited rather than the product of solar radiation, as other natural philosophers of the time believed. It can be observed that a straight line is obtained when the pressure exerted by the gas (P) on the Y axis and the reciprocal of the volume occupied by the gas (1/V) is taken on the X axis. Here, P1 and V1 represent respectively the pressure and the original volume, and P2 and V2 represent the second pressure and the second volume. This equation shows that as the volume increases, the gas pressure decreases proportionally.
