• # question_answer A Container having 1 mole of a gas at a temperature 27°C has a movable piston which maintains at constant pressure in container of 1 atm. The gas is compressed until temperature becomes 127°C. The work done is (Cp for gas is 7.03 cal/molK)                                  A) 703 J B) 814 J C) 121 J D) 2035 J

[b]        At constant pressure $W=P\Delta V=\mu R\Delta T$$=1\times 8.31\times 100$$=831\approx 814J$
