What does increased specific gravity mean?

Answer 1

Increased density via increased mass or decreased volume or both.

The specific gravity (also called relative density) of a substance is the ratio of the density of that substance to the density of water at #4^@C#, at which temperature water has its maximum density.

#therefore SG=rho_(rel)=rho_s/(rho_(H_2O at 4^@C)#.

So if the specific gravity increase, it means the density of the material has increase and since density is the mass per unit volume (#rho=m/V#), there are different ways this is possible - either the mass increases or the volume decreases, or both. (Example in a black hole, as the mass increases and volume decreases, so the density increases and so the specific gravity also increases).

Increased specific gravity indicates higher concentration of solutes in a fluid, often observed in urine, suggesting dehydration or kidney-related issues.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
