Enthalpy and entropy at phase transition
The second law of thermodynamics states, that entropy (of the universe) always increases. Entropy can, however, be (locally) reduced when energy is provided.
At the phase transition from a relatively ...

Why $|H_1(\Sigma,\mathbb{Z}_N)|$ can be interpreted as an 1+1d $\mathbb{Z}_2$ gauge theory?
I am reading the article https://arxiv.org/abs/2204.02407, and I am struggling with the definition of a condensation defect, which is given by
\begin{align}
S(\Sigma)=\frac{1}{\sqrt{|H_1(\Sigma,\...

Why does dew only fall on horizontal surfaces?
I noticed that dew only falls on horizontal surfaces, while vertical surfaces remain dry.
But dew is the condensation of water vapor contained in the air. And for the condensation process, the ...

Clausius-Clapeyron relation for high pressures
I can see that the Clausius-Clapeyron relation depends on the change in specific volume $\Delta v = v_g (1 - \frac{v_c}{v_g}) = v_g - v_c$, with $v_c$ equal to the volume of the condensed phase and $...
