Question #f4070
1 Answer
Given
#n->"number of moles of the gas"=1mol# #P_i->"Initial pressure of the gas"=10atm# #P_f->"Final pressure of the gas"=1atm# -
#T->"Temperature of the gas"=27^@C=300K# -
#R->"Universal gas constant"#
#" "=2calK^-1mol^-1xx4.184J/"cal"#
#" "=8.368JK^-1mol^-1# #R->"Universal gas constant"=0.082LatmK^-1mol^-1#
The expansion may be done in two different paths
1) Isothermal reversible
2) Isothemal irrevresible
1) For Isothermal reversible expansion
work done
2) For Isothermal Irreversible expansion
work done
PLEASE NOTE
The second part should be our answer as per given problem.
Since the expansion has been brought about under constant pressure of
