Entre los siguientes métodos de separación de mezclas, Jorge debe seleccionar el adecuado para separar sal de una mezcla de sal
makvit [3.9K]

Teniendo en cuenta las definición de evaporación, la respuesta correcta es la primer opción: para separar la sal, Jorge debe usar la Evaporación, porque con este método se evapora el agua y queda únicamente la sal.

El método de separación utilizado para el agua y la sal es: la evaporación.

La evaporación consiste en pasar el soluto disuelto en un liquido a estado gaseoso y ocurre al aumentar su temperatura de forma natural o artificial,. Dependiendo de que se desea evaporar se utiliza el material correspondiente. La técnica mas común es por contacto y puede acelerarse si utilizamos un material conductor dentro del liquido.

En otras palabras, se conoce que la evaporación es el proceso por el cual las distintas moléculas en estado líquido, como lo es en agua, pasan a un estado gaseoso de manera espontánea, siendo este el principal efecto de la evaporación.

Como se mencionó el método de separación utilizado para el agua y la sal es la evaporación. Durante este proceso, al aplicar calor, el agua se convierte en vapor y se libera al aire. La sal, como tiene otro punto de ebullición, no se evapora.

Entonces, la respuesta correcta es la primer opción: para separar la sal, Jorge debe usar la Evaporación, porque con este método se evapora el agua y queda únicamente la sal.
