e. Lead
Explanation:
Hello,
In this case, since the equation to compute the heat in a heating or a cooling process is:
We can see that the lower the specific heat of the substance, the higher the reached temperature as they are in an inversely proportional relationship. In such a way, we can say that e. Lead will reach the higher temperature if the same heat is added to same mass of the other metals.
Regards.
Ответ:
Existen magnitudes básicas y derivadas, que constituyen ejemplos de magnitudes físicas: la masa, la longitud, el tiempo, la carga eléctrica, la densidad, la temperatura, la velocidad, la aceleración y la energía. En términos generales, es toda propiedad de los cuerpos o sistemas que puede ser medida. De lo dicho se desprende la importancia fundamental.
