Question

what happen if we will put an eraser in saltwater?
please answer fast it's so urgent. ​

Answer 1

Explanation:

Adding salt to water makes the water denser . As the salt dissolves in the water. it adds mass ( more weight to the water ). This makes the water denser and allows more objects to float on

the surface that would sink in fresh water.

Answer 2

The rubber duckie floats because the weight of the water it pushes away is equal to the upthrust. The eraser is heavier than the amount of water it pushes away. Since the upthrust is smaller than its weight, the eraser sinks.
