مالذي يحدث إذا كان البحر أو الماء مالحا.

09 أبريل 2014

ماهما الإمكانان اللذان يجعلان جسما غارقا يطفو؟

يتمثل الأول في تكبير مقاييسه دون تغيير وزنه.

ويتمثل الثاني في إذابة الملح في الماء كي يصبح "أثقل".

تغرق البيضة في الماء العذب لكنها تطفو في الماء المالح.

ملوحة البحر الميت مرتفعة جدا مما يسمح لشخص ثخن بالإسترخاء فوق الماء، كما لو كان على السرير، ومطالعة كتاب دون أن يغرق.
