Question
Three samples of same gas initially having same volume and at same pressure are expanded to double its initial volume, sample A is expanded isothermally, B adiabatically and C isobarically. In which case minimum work is done?
Solution
In an adiabatic expansion, the temperature of the gas would drop. therefore, work done is positive. Hence, W is positive. Therefore, the minimum work is done in the case of adiabatic expansion.
