What is the
can someone help me solve
this? or give me some insight
on how to solve it. It also
asks what the change of the
universe (system) and
(surrounding) are. I just cant
seem to figure it out. Thanks

To solve this first you have to know two equations 1) ΔU = E - W (change in internal Energy) = (Energy gained by system) - (work done by the system) 2) W= ΔV*P (work done by system) = (change in volume)*(pressure) ---- E is given, 312J, since this is given off and not gained we will enter it as (-) 312J --- now to find W For volume change we are told it is a compression of 862ml... we need to convert this to L (so divide by 1000) and note that it is compression so the ΔV will be negative. ΔV = (-).862L and of course Pressure = 1.64atm... but once again this is in the wrong units so we ahve to convert from atm to Pascals ( so multiply by 101,325) P = 166,173 Pa Now we plug into equation 2: W=ΔV*P W=(-).862L *166,173 Pa W= (-)143,241.1J ---- Now put it all together in eq 1 for the final answer ΔU = E - W ΔU = (-312J) - (-143,241.1J) ΔU = (+)142,929.1J I am assuming the second part of your question reffers to to basic thermodynamics in that, the E change for the system which is ΔU is equal to the - ΔE of the surronding enviroment. so since the system gained ~143KJ the surroung enviroment (or universe if you will) must have lost ~143KJ.... hope that clears thigns up for you. |
