Pregunta 1
Pregunta
What is the first law of thermodynamics
Respuesta
-
If two objects A and B are in thermal equilibrium with a third object C, then A and B
-
Conservation of energy in thermal physics
-
The entropy of a perfect crystal at absolute zero is exactly equal to zero
-
Entropy of an isolated system can stay the same Conservation of energy in thermal physics or increase. It can never decrease.
