Adiabatic Compression Pressure ( P) > Volume (V) T, S, and U increase during compression. In cylinders of a car, the compression of the gas-air mixture takes place in no time that there could be an exchange of heat between them. Adiabatic Expansion The work is done by the gas in expanding the volume … See more Consider a mole of gas contained in a cylinder having insulating walls, provided with a frictionless and insulating piston Let P be the pressure of the gas when the piston moves up through a small distance dx, the work done will … See more We already know that for an ideal gas, the equation is given by, PV = RT ( for one mol gas) V = RT/P…(1) Putting the value of equation (1)....in the … See more Adiabatic relationship between P and V According to the first law of thermodynamics: dQ = dU + dW….(1) For one mole of gas, the equation is: dW = PdV dU = nCVdT, and CV= dU/dT => dU = nCVdT = CVdT (as … See more For one mole of gas, PV= RT P =RT/V Putting PV r=G, we get RT/V * Vr= G or T*V(r - 1)= G/ R = TV(r - 1)= G (Constant) This equation describes the adiabatic relation between V … See more WebSep 9, 2024 · From these it is easy to see that the ratios of the adiabatic, isothermal, isobaric and isochoric slopes are as follows: For example: - isothermal: PV = constant. Take … WebSep 12, 2024 · When an ideal gas is compressed adiabatically \((Q = 0)\), work is done on it and its temperature increases; in an adiabatic expansion, the gas does work and its … mummys wine glass
