Grade 11 Thermodynamics Question

[QUOTE="Simon Bridge, post: 5463663, member: 367532"] No, when I say please answer the questions in post #2 I mean [I]answer the questions in post #2[/I]. None of those lines answer the questions in post #2? Lets do it one at a time: 1. How much energy is released lowering the steam to 100deg? The idea here is to make sure you understand the process. Aside: check your values for specific and latent heats ... check units etc. i.e. I have L_f = 334 kJ/kg = 3.34x10[sup]5[/sup] J/kg from [URL]http://www.engineeringtoolbox.com/water-thermal-properties-d_162.html[/URL] Compare with yours. The numbers in post #5 seem to assume the initial temp of the steam is 160deg (that is not what post #1 says) and that the specific heats are the same across phase changes, and that all the steam and all the ice ends up as water.
