Se desarrolla una técnica de resonancia acústica y de microondas para la caracterización de mezclas de gases energéticos no convencionales y para realizar una termometría acústica en Argón. La resonancia de microondas se lleva acabo simultáneamente con la acústica para caracterizar el radio interno del resonador esférico y reducir así la incertidumbre en la velocidad del sonido en Argón. Se realizan medidas de la velocidad del sonido en Argón a diferentes presiones manteniendo siempre la temperatura constante a la temperatura del punto triple del agua. Al extrapolar la isoterma a presión nula se pueden obtener medidas con muy baja incertidumbre (aproximadamente 20 ppm) de la constante de Boltzman para la definición del nuevo Kelvin. Con u...
