Question

Why ship will rise when it going from river to sea?

Answer 1

When the ship enters the sea, the water is no more the river fresh water but the saline sea water which is denser. As a result the weight of water displaced is now more than what it was previously when the ship was inriver. The upthrust increases and theship rises up.

Hope it'll help you ^_^
