Base words and phrases: ideal gas, real gas, laws, diagram The ideal gas laws are a set of laws that describe the behavior of an ideal gas at different conditions. An ideal gas is a theoretical gas composed of a large number of identical particles that are not subject to intermolecular interactions, have no volume, and have completely elastic collisions. there are three laws that are commonly referred to as ideal gas laws:1. Boyle's law: This law states that when the pressure of a given mass of a gas is inversely proportional to its volume, while its temperature is held constant. In mathematical terms, this can be expressed as PV = constant, where P is the pressure, V is the volume, and the product PV remains constant.2. Charles's law: This law states that at a constant pressure, the volume of a given mass of a gas is directly proportional to its absolute temperature. It can be mathematically expressed as V/T = constant, where V is the volume, T is the temperature, and the ratio V/T remains constant.3. Avogadro's law: This law states that equal volumes of gases at the same temperature and pressure contain the same number of particles. In mathematical terms, this can be expressed as V/n = constant, where V is the volume, n is the number of particles, and the ratio V/n remains constant.These three laws can be combined to form the ideal gas law, which states that the pressure, volume, and temperature of an ideal gas are related by the equation PV = nRT, where P is the pressure, V is the volume, n is the number of particles, R is the ideal gas constant, and T is the absolute temperature. 3. Real gas laws. Base words and phrases: ideal gas, real gas, laws, diagram Created in the early 17th century, the gas laws have been around to assist scientists in finding volumes, amount, pressures and temperature when coming to matters of gas. The gas laws consist of three primary laws: Charles' Law, Boyle's Law and Avogadro's Law (all of which will later combine into the General Gas Equation and Ideal Gas Law). Introduction The three fundamental gas laws discover the relationship of pressure, temperature, volume and amount of gas. Boyle's Law tells us that the volume of gas increases as the pressure decreases. Charles' Law tells us that the volume of gas increases as the temperature increases. And Avogadro's Law tell us that the volume of gas increases as the amount of gas increases. The ideal gas law is the combination of the three simple gas laws. Ideal Gases Ideal gas, or perfect gas, is the theoretical substance that helps establish the relationship of four gas variables, pressure (P) , volume(V), the amount of gas(n)and temperature(T). It has characters described as follow: 1. The particles in the gas are extremely small, so the gas does not occupy any spaces. 2. The ideal gas has constant, random and straight-line motion. 3. No forces between the particles of the gas. Particles only collide elastically with each other and with the walls of container. Download 1.46 Mb. Do'stlaringiz bilan baham: |
