Find free online Chemistry Topics covering a broad range of concepts from research institutes around the world. Liquefaction of Gases For important commercial operations such as LPG and rocket fuels, we require gases in their liquid state. The liquefication methods are based on the Joule-Thomson effect. He observed appreciable cooling when the compressed gas is forced through … [Read more...] about Liquefaction of Gases

Find free online Chemistry Topics covering a broad range of concepts from research institutes around the world. Pressure-Volume Isotherms of Carbon Dioxide Andrew's Isotherm Thomas Andrew gave the first complete data on pressure-volumetemperature of a substance in the gaseous and liquid states. He plotted isotherms of carbon dioxide at different temperatures which is shown … [Read more...] about Pressure-Volume Isotherms of Carbon Dioxide

Find free online Chemistry Topics covering a broad range of concepts from research institutes around the world. Deviation form Ideal Gas Behaviour The kinetic theory of gases (postulates of kinetic theory of gases are described in physics text book) which is the basis for the gas equation (PV=nRT), assumes that the individual gas molecules occupy negligible volume when … [Read more...] about Deviation form Ideal Gas Behaviour

Find free online Chemistry Topics covering a broad range of concepts from research institutes around the world. Mixture of Gases - Dalton's Law of Partial Pressure Studies of non-reacting gaseous mixtures showed that in a gaseous mixture each component behaves independently. For a gaseous mixture, it is important to know, how the pressure of individual component contributes … [Read more...] about Mixture of Gases – Dalton’s Law of Partial Pressure
