Module 20: second law of thermodynamics

WebEnergy (1st law of thermodynamics), the 2nd law of thermodynamics and the property relations. Energy can be viewed as the ability to cause changes. First law of thermodynamics: one of the most fundamental laws of … Web21 jun. 2024 · So, as Hawking realised, we can apply all of Thermodynamics to a black hole. In a previous section we saw that any body with a temperature above absolute zero will radiate energy. And we have just seen that a black hole has a non-zero temperature. Thus thermodynamics says it will radiate energy and evaporate.
