	Se presenta una demostración de aula que muestra que el vapor de un líquido tiene mucha mayor tendencia a expandirse por calentamiento que un gas, y que la presión de vapor es muy sensible a la temperatura porque tiene una dependencia exponencial con esta. Además se muestra que un aumento de temperatura provoca un desplazamiento del equilibrio hacia estados de mayor entropía.
