A motor draws some gas from an adiabatic container of volume 2 liters having a monoatomic gas at a pressure 4 atm. After drawing the gas the pressure in the container reduces to 1 atm. If the motor converts `10%` of the energy contained in the drawn gas and the output of the motor is 10 p joule, then find the value of p.use `(1atm=10^(5)` pascal) |

Answer» Correct Answer - 9 Initially internal energy of the gas in the container `=fnRT` `//2=fPV//2=3PV//2` `=3xx4xx2//2=12` atm-litre finall internal energy of the gas in the container `=3xx1xx2//2=3atm`. Litre energy of the gas drawn `=9atm-I=900J` Output of the motor `=10%` of `900=90J` |
