Elementary Errors Heat

Click For Summary

The discussion highlights common misconceptions in heat transfer at an elementary level, particularly regarding the distinctions between integrals and changes in quantities. It emphasizes that the integrals of heat (∫dQ) and work (∫dW) do not equal the changes in heat (ΔQ) and work (ΔW), but rather represent total heat (Q) and work (W). In contrast, the integral of internal energy (∫dU) does equal the change in internal energy (ΔU). The post is well-received, contributing valuable insights to the Frequently Made Errors series. Understanding these distinctions is crucial for grasping fundamental concepts in thermodynamics.

Excellent. Also one of the most made mistakes are ∫dQ and ∫dW not equal to ΔQ and ΔW They equal Q and W but ∫dU=ΔU.

Thread 'Can somebody explain this: Planck's Law in action'

Plotted is the Irradiance over Wavelength. Please check for logarithmic scaling. As you can see, there are 4 curves. Blue AM 0 as measured yellow Planck for 5777 K green Planck for, 5777 K after free space expansion red Planck for 1.000.000 K To me the idea of a gamma-Ray-source on earth, below the magnetic field, which protects life on earth from solar radiation, in an intensity, which is way way way outer hand, makes no sense to me. If they really get these high temperatures realized in...
