LEY DE GAY LUSSAC

SEGUNDO “A” (BGU)

2012-2013EXPERIMENTO SOBRE LA LEY DE GAY-LUSSAC
MARCO TEORICO
Gay Lussac dice que “cuando el volumen se mantiene constante, las presiones que ejercen los gases son directamente proporcionales a sustemperaturas absolutas”
MATERIALES
Dos recipientes
Agua caliente
Agua fría
Botella de plástico
Globo de caucho
PROCEDIMIENTO
1. Colocamos en el primer recipiente el agua caliente y en el segundo el aguafría

2. Tomamos la botella de plástico y colocamos el globo de caucho en el pico de la misma.

3. Cogemos la botella y la sumergimos en el agua fría, dentro de unos pocos segundos podemosobservar como el globo se infla


4. Retiramos la botella del agua caliente y la sumergimos en el agua fría, esperando así mismo pocos minutos observamos como poco a poco el globo de va desinflando.CONCLUSION
Al realizar este experimento se puede comprender mejor la ley de Gay Lussac examinando así: el gas en este caso el oxígeno se expande con el aumento de la temperatura ocupando másespacio, lo que provoca que el globo se infle mientras que con la disminución de la temperatura este se comprime lo que provoca que el globo se desinfle.hvjugwbvjbfyuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu-
