Q. When a ship enters a sea from a river, what happens?
When a ship enters a sea from a river, the ship is elevated due to the higher density of the salty seawater than the river.
On average, seawater in the world's oceans has a salinity of approximately 3.5%, or 35 parts per thousand. This means that for every 1 liter (1000 mL) of seawater there are 35 grams of salts (mostly, but not entirely, sodium chloride) dissolved in it. Rivers and lakes can have a wide range of salinities, from less than 0.01 g/kg to a few g/kg, although there are many places where higher salinities are found. That is the reason why a ship rises a little when enters a sea from the river.
- It rises a little
- It remains at the same level
- It sinks a little
- It immersed in the bottom of the sea.
Answer: It rises a little.
