Post by Darwin420 » Wed Oct 29, 2008 10:37 pm

What is w when 2.83 kg of H2O(l), initially at 25.0oC, is converted into water vapour at 109oC against a constant external pressure of 1.00 atm? Assume that the vapour behaves ideally and that the density of liquid water is 1.00 g/mL. (Remember to include a "+" or "-" sign as appropriate.)

Enter your answer in acceptable SI units, accurate to 3 significant figures. Use an acceptable SI abbreviation for units!

Your Answer: -212 J

ok, I am having great difficulties solving this stuff. I must be missing some minor details. Help?
