Supposing all the "gas" is water vapor. The source below gives the specific heat of water vapor and liquid water: (2.000 J/(g·°C) x ((0.07796 g) x (125 ºC - 100 ºC) = 3.898 J from cooling the vapor to 100 ºC (0.07796 g H2O) / (18.01532 g H2O/mol) =
Thank you both.
I'm not too sure how to add the latent heat part in there, but I'll reread that section in my book and see if I can figure something out.
The specific heat of ice and water is given as 2.06 kJ/(kg K) and 4.19 kJ/(kg K) respectively.
The answers are 21.9 degree c and 14.2 degree c. I've tired figuring out a way to use the dE = Q - W equation to solve this problem, but it hasn't been working.
