Transcript of Kinetic Theory of Gases

Para medir la presión de vapor del Tungsteno a 4500K se ha utilizado una equipo de efusión de Knudsen, que consiste en una balanza de precisión dentro de un horno de alta temperatura.

La muestra se introduce en una celda con un pequeño orificio. Se mide entonces la velocidad con la muestra pierde peso por desprendimiento de vapor, y que es directamente proporcional a la presión de vapor del material.

En el experimento, la muestra pierde 2.113 g por hora. El área del orificio es de 1 mm2.
Celda de Knudsen
