Se tienen 5 cm3 de aire encerrado en una jeringa, siendo p = 760
mmHg. Para reducir el volumen que ocupa el gas se ejerce presión,
manteniendo constante la temperatura:
a- Calcula qué presión habrá que ejercer sobre el émbolo de la
jeringa para que el volumen sea una décima parte menor que el inicial.
b- ¿En cuánto debe aumentar la presión para que el volumen se
reduzca a la mitad?
