in isothermal process and in adiabatic process heat transfer is zero so re these process same?
1 Answer
Let it be x
We define specific heat asC=ΔQΔTC=ΔQΔTIn case of isothermal process, if the heat supplied is compensated by P-V work done, then the temperature of the gas will not increase. So, ΔT=0ΔT=0. Then, C=∞C=∞.In case of adiabatic process, however, ΔQ=0ΔQ=0, as you cannot supply heat from outside. Therefore, C=0C=0.However, when we want to calculate the amount of work done, in adiabatic process, we write W=CvΔTW=CvΔT (for ideal gas). But CvCv should be 00. But that does not make any sense.
