PPT-Gas Temperature, Volume, and Pressure

This tool can measure the temperature volume and pressure of a gas What is temperature All particles in all things are moving at all times but some faster than others Temperature measures the average speed of the particles in something. Introduction and Gases . Physics - study of the properties of matter that are shared by all substances. Chemistry - the study of the properties of the substances that make up the universe and the changes that these substances undergo. Gas Pressure. Just means that gas is “pushing” on something.. Gas Pressure. Tire . What’s going on inside?. Air:. Nitrogen 78%. Oxygen 21%. Argon ~1%. Carbon Dioxide <1%. Each of these particles are constantly flying around. Like a lotto ball!. Gas Pressure. Just means that gas is “pushing” on something.. Gas Pressure. Tire . What’s going on inside?. Air:. Nitrogen 78%. Oxygen 21%. Argon ~1%. Carbon Dioxide <1%. Each of these particles are constantly flying around. Like a lotto ball!. Under water, the pressure on a diver is greater than the atmospheric pressure.. The combined gas law comes from the pressure–volume–temperature relationships for gases that we have studied. . Learning Goal . Ideal versus Real Gases. An ideal gas adheres to the Kinetic . Molecular Theory . exactly in all situations.. Real gases deviate from ideal behavior at . high. pressures and . low. temperatures.. When the pressure is . PV=nRT. The ideal gas law can be applied to most gas law problems.. Keep in mind that if a condition does not change, it can be considered a constant.. Ideal Gas Law. If a sample of gas occupies a 400ml vessel which has a pressure of 5.2 atm, has the volume increased to 2.4L, what is the new pressure of the vessel?. Section 14.1 – Properties of Gases. Compressibility. is a measure of how much the . volume. of matter . decreases. under pressure.. Gases. are compressible because the particles are . far apart. The SI unit of pressure is the . pascal. (Pa).. . One . standard atmosphere (. atm. ). is the pressure required to support 760 mm of mercury in a mercury barometer at 25°C. . 13.1. 13.1. 13.1. 13.1. Gay-Lussac’s Law of Combining Volumes. At constant temperature and pressure, the volumes of gaseous reactants and products can be expressed as ratios of small whole numbers.. In other words, in stoichiometric calculations, the coefficients may be used as Volume Ratios instead of molar ratios, IF both compounds involved are gases AND they are at the same temperature as each other.. (. Gay-Lussac’s Law). Gay-Lussac’s law: . When . the . Kelvin temperature . of a . gas doubles . at constant volume and amount of gas, the pressure also doubles.. Learning Goal . Use the temperature–.
