How mirror can be identified by observing the values of the magnification?

How mirror can be identified by observing the values of the magnification? If an object is placed within the focal length of a mirror, the image of the object will get magnified in case of a concave mirror, and will get diminished in case of a convex mirror. The value of magnification will be greater than 1 in case of a concave mirror, and less than 1 in case of a convex mirror.

Simple distillation

If we want to obtain the solvent from a solution, then the process of distillation can be carried out. The apparatus used in this process is shown in Figure.



Water can be obtained from saltwater using this method. The solution is heated in the flask until it boils. The steam rises into the Liebig condenser, where it condenses back into the water. The salt is left behind in the flask. In hot and arid countries such as Saudi Arabia, this sort of technique is used on a much larger scale to obtain pure water for drinking. This process is carried out in a desalination plant.
