Se le pide calcular la potencia electrica (en kWh) necesaria para calentar un alambre de aluminio (colocado en un vacio como si fuera el filamento de una bombilla) desde 25°C hasta 660°c (liquido) para usarse en un aparato de deposicion de vapor. El punto de fusion del Al es de 660°C. El alambre tiene 2.5 mm de diametro y 5.5 mm de longitud. (La deposicion de vapor se realiza a temperaturas cercanas a 900°C.)
