Indica que enunciados son falsos y redáctalos de manera que sean verdaderos. - Thomson descubrió el electrón en un tubo de descarga de gases con el cátodo perforado.
- Millikan observó que la carga del electrón es un múltiplo exacto de una carga elemental.
- En un tubo de descarga de gases, los protones viajan desde el cátodo al ánodo.

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
