Photon energy and specific heat capacity

Fluxthroughme · Mar 6, 2013

Handwritten worked solution for textbook problem 38.57: q = mcΔT = 2x10^-9 x 4190 x 67 = 5.615x10^-4 J; q = mL = 2.256x10^6 x 2x10^-9 = 4.512x10^-3; total q = 1.013x10^-3 J; then parts b and c started as P = E/t and γ/s = P/E_γ.

If I use the answer given in the book for part a, I can get the correct answers for b and c. However, I do not know what I have done wrong in part a? My best guess would be that assuming the blood evaporates at 100 degrees is incorrect? The answer given in the book is [itex]5.1*10^{-3}J[/itex]

It seems correct to me... and if they ask you to use same data as water, I also assume that using 100°C is correct as vaporization point (also because you do not have it given, and you would need it to do the problem, so it has to be 100°C).

Perhaps the book has wrong solutions, or something else is going on I can't see, but to me it is correct
