Why any object sink in salt water not in fresh water ? |
|
Answer» Salt water has greater density then fresh water The dissolved salt increases the mass of the water without increasing its volume, so salt water is generally denser than fresh water. This means the buoyant force on a submerged or partially submerged object is greater in salt water than in fresh water. In other words, it\'s easier to float in salt water than in fresh water (or, you sink faster in fresh water than in salt water). |
