    What's the use of density here?

    yeah they only said pV=constant. The density is on the Initial.

    I don't think it has any use. W=pVln(P1/P2) W=(95)(0.045)ln(95/190) W=-2.96 kJ Then, Using : ΔU=Q-W =-2.96kJ - (-2.96kJ) =0 kJ But I'm not sure about it

    Oh. Sorry... The problem is "What is the change in internal energy of ethane

    What's the use of density here?

    Pressure initial: 95 kPa Final pressure: 190 kPa Change in enthalpy: -2.96 kJ Initial volume: 0.045 cu.meter Density: 1.11 kg/cu.meter pV=c

    Is heat removed a form of change in enthalpy?

    Can "heat removed" be considered as change in enthalpy?
