Question

Why an egg sinks in fresh water, but floats in a strong salt solution


ICSE Class 9 Physics Chapter Upthrust in Fluids,Archimedes Principle and Floataion

Answer 1

hey

_____________

•buoyancy - depends on density of fluid ( it determines whether the object will sink or not )

•buoyant force is directly proportional to density

•higher the density of fluid , higher the object floats over it

•lesser the density of fluid , lesser it floats over it

•when the object density is less or equal to water then it will float , when object denisty is more than water then it sinks ,

•so here we can say that egg must havebeen having more density than water (1.0 ×10^3 g ) so it sinks

hope helped

The ability of something, float in water or some other liquid is known as buoyancy.

The density of salt water is more than that of fresh water which results in more buoyancy.

The density of the egg is higher than the density of tap water, so it sinks.

When salt is added to the water, the saltwater solution's density becomes higher than the egg's, so the egg will then float.
