Salt can be used to preserve food by drawing out moisture and creating an inhospitable environment for bacteria growth. In this way, salt can be used to extend the shelf life of perishable items without the need for refrigeration. However, it is limited in its effectiveness and not suitable for all types of food.

The time it takes to evaporate half a cup of salt water depends on various factors such as temperature, humidity, air circulation, and surface area. On average, it could take several hours to a day for half a cup of salt water to fully evaporate.
To evaporate water from salt water, you can heat the salt water to cause the water to evaporate and leave the salt behind. This process is known as distillation. The steam generated from the boiling water can be collected and condensed back into freshwater, leaving the salt behind.
To separate a mixture of copper fillings and salt, you could use a magnet to attract the copper fillings, since copper is a magnetic material, while salt is not. By moving the magnet through the mixture, the copper fillings will stick to the magnet, allowing you to separate them from the salt. Another method could involve dissolving the salt in water, leaving the copper fillings behind, and then using filtration to separate the two components.
