    Here pressure =0.6 L ,Wco2=22gm ,T=298 K

    eduncle-logo-app

    then pressure before and after will be same na

    eduncle-logo-app

    when ice become gas then pressure will increase due to evaporation

    eduncle-logo-app

    when we take value of R 8.314 and when 0.0821

    eduncle-logo-app

    here pressure exerted by Co2 inside the vessel is calculated...we use here ideal gas equation

    eduncle-logo-app

    and pressure inside container= pressure exerted by Co2 + atmospheric pressure

    eduncle-logo-app

    r value?

    eduncle-logo-app

    check R value in diff units

    eduncle-logo-app

    L atm mol^-1 K^-1 ...so 0.0821 is used... in option see atm is given.. volume is in Litre...so you can identify like this also
