Photon energy and specific heat capacity

Click For Summary
SUMMARY

The discussion centers on the calculation of photon energy and specific heat capacity, specifically addressing a discrepancy in part a of a problem related to blood evaporation. The participant questions the assumption that blood evaporates at 100 degrees Celsius, which aligns with the vaporization point of water. The book provides an answer of 5.1*10^{-3} J, which the participant believes is correct, indicating potential errors in the book's solutions or a misunderstanding of the problem requirements.

PREREQUISITES
  • Understanding of photon energy calculations
  • Knowledge of specific heat capacity concepts
  • Familiarity with the vaporization point of water
  • Basic thermodynamics principles
NEXT STEPS
  • Research the relationship between photon energy and temperature in thermodynamics
  • Study the specific heat capacity of various substances, including blood
  • Learn about the phase changes of water and their implications in thermodynamic calculations
  • Examine common errors in textbook solutions related to heat transfer problems
USEFUL FOR

Students in physics or chemistry, educators teaching thermodynamics, and professionals involved in biophysics or biomedical engineering.

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
