1. Usar la fórmula del punto de rocío:
T_d = T - \left( \frac{100 - RH}{5} \right)
2. Sustituir \( T = 25 \) y \( RH = 55 \):
T_d = 25 - \left( \frac{100 - 55}{5} \right) = 25 - 9 = 16 \text{ °C}
3. Comparar la temperatura de los anteojos (12 °C) con el punto de rocío (16 °C):
12 \text{ °C} < 16 \text{ °C}
Conclusión: Los anteojos se empañarán.
