    A fresh egg sinks in pure water but floats in salt water. This is because:

    A)  Saline water is denser than pure water

    B)  Saline water is lighter than pure water

    C)  The viscosity of saline water is higher than that of pure water

    D)  None of these

    Correct Answer: A

    Solution :

    [a] An egg is more-dense than regular water; therefore, the egg will sink. But when you add salt to the water, you are making the solution more-dense. The salt water's density becomes greater to the point that it is more-dense than the egg. Because the egg is now LESS dense than the water, it floats.
