For the isothermal expansion of an ideal gas
WebJan 30, 2024 · To derive the equation for an isothermal process we must first write out the first law of thermodynamics: ΔU = Q + W Rearranging this equation a bit we get: Q = ΔU + W Since ΔT = 0. Therefore we are only left with work: Q = W As such we get: W = − pΔV Making this equation into an ideal gas equation we get: W = nRt V WebJan 30, 2024 · Isothermal Expansion This shows the expansion of gas at constant temperature against weight of an object's mass (m) on the piston. Temperature is held constant, therefore the change in energy is zero (U=0). So, the heat absorbed by the gas equals the work done by the ideal gas on its surroundings.

http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/isoth.html WebIsothermal Expansion Free expansion of a gas occurs when it is subjected to expansion in a vacuum (pex=0). During free expansion of an ideal gas, the work done is 0 be it a reversible or irreversible process. It is known that the change in internal energy of a system is given as: ∆U = q + w —(1)
WebFigure 3.15 Quasi-static adiabatic and isothermal expansions of an ideal gas. The dashed curve shown on this pV diagram represents an isothermal expansion where T (and therefore pV) is constant. The slope of this curve is useful when we consider the second law of thermodynamics in the next chapter. This slope is d p d V = d d V n R T V = − p V. WebWe have already shown that the expansion coefficient of an ideal gas is 1/ T, and the isothermal compressibility of an ideal gas is 1/ P. Note that, for an ideal gas, β = 1/ T and κ = 1/ P, so that equation 13.3.2 reduces to R. Note that, in equation 13.3.2, κ is the isothermal compressibility.
