If stranded on a deserted island with no freshwater it is not advisable to drink sea water. why not?

It is not advisable to drink sea water, and instead, convert it into fresh water, because the human can only take in a certain amount of salt. Salt water actually is more harmful than not drinking water, as it can damage the internal organs, as well as continually make you thirsty. Instead, you'll have to build a strainer, and clean as much of the salt from the ocean as possible, before drinking it.

hope this helps

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
