Why there is a temperature change in adiabatic process?
Dec 28, 2016 · 1 I am learning the topic thermodynamics and I came to know that in an adiabatic process the heat of the system remains constant. So is it a hard and fast rule that temperature will …
Why is there no work in a free and adiabatic expansion of a gas?
Apr 16, 2024 · I recently came across the topic of irreversible expansion in thermodynamics. Suppose we have a container of gas with a piston (not mentioned whether massive or not), and we allow a …
Adiabatic expansion of gas - Chemistry Stack Exchange
Aug 8, 2020 · First note that the process is an irreversible adiabatic expansion. If it were a reversible one, the gas has to expand against a varying pressure because pressure of gas decreases during …
physical chemistry - Mathematical proof that more work is done in an ...
May 24, 2024 · Is it possible to mathematically prove that expansion work done in an adibatic process is less than that of an isothermal process?
Why is the enthalpy change not zero in an adiabatic process?
Jan 5, 2014 · Isn't enthalpy defined for systems at constant pressure, so the V∆P part in the second line is itself zero. That gives us ∆H=0 for an adiabatic process.
thermodynamics - irreversible adiabatic process against constant ...
May 30, 2018 · The ideal gas law describes the behavior of an "ideal gas" only under thermodynamic equilibrium conditions. For a rapid irreversible expansion or compression, the gas is not close to …
thermodynamics - How to calculate the final temperature of a gas …
Mar 16, 2017 · It undergoes an adiabatic expansion against a constant external pressure of $\pu {79.8 kPa}$, until the volume has increased by a factor of $3$. Calculate the final temperature.
Alternative Explanation to Why is Entropy Zero in a Reversible ...
Mar 22, 2025 · In an adiabatic expansion heat is not exchanged with the surroundings and is therefore not provided as a source to generate entropy. Instead the increase in volume increases the ways of …
physical chemistry - Entropy change in an adiabatic expansion ...
May 8, 2015 · If the expansion is done reversibly, then we know entropy of the universe can't be changing (because reversible), and that heat flow from the gas to the surroundings is zero (because …
physical chemistry - adiabatic expansion vs Joule-Thomson Effect ...
Jan 16, 2019 · I am looking for difference between adiabatic expansion and Joule-Thomson effect. Looking at the setup demonstrating Joule-Thomson effect, I find no essential difference between the …
