T S Diagram Enthalpy - enthalpy n l p i a property of a thermodynamic system is equal to the system s internal energy plus the product of its pressure and volume in a system enclosed so as to prevent matter transfer for processes at constant pressure the heat absorbed or released equals the change in enthalpy history the diagram was created in 1904 when richard mollier plotted the total heat h against entropy s at the 1923 thermodynamics conference held in los angeles it was decided to name in his honor as a mollier diagram any thermodynamic diagram using the enthalpy as one of its axes thus r h 176 f h 176 gypsum f h 176 anhydrite f h 176 water 16 86 kj mol exothermic vs endothermic if r h 176 lt 0 the reaction produces a reduction in enthalpy and is exothermic heat is given up by the rock and gained by the surroundings if r h 176 gt 0 the reaction produces an increase in enthalpy and is endothermic heat from.
the surroundings is consumed by the rock let me draw a good old pv diagram that s my pressure axis this is my volume axis just like that i have pressure and volume i showed several videos ago that if we start at some state here in the pv diagram right there and that i change the pressure and the volume to get to another state and i do it in a quasistatic way so essentially i m always close to equilibrium so my state choose a fluid or refrigerant which vaporizes at a lower temperature than the space to be cooled heat then flows from the cool space downhill and vaporizes the refrigerant this website and its content is subject to our terms and conditions tes global ltd is registered in england pany no 02017289 with its registered office at 26 red lion square london wc1r 4hq this is a formal presentation of the formul 230 that describe those properties of water vapour in air that concern.
conservators the derivation of these equations is explained concisely and the useful equations are emphasised by bold type this datasheet is intended for gold standard mcat prep s mcat general chemistry review summary cheat sheet notes
