Diabetes can alter the density of urine, so urine density can be used as a diagnostic tool. Diabetics can excrete too much sugar or excrete too much water. What do you predict will happen to the density of urine under each of these conditions? (Hint: Water containing dissolved sugar is more dense than pure water.)

Interpretation Introduction

Interpretation:

The density of urine under given conditions has to be predicted.

Concept introduction:

Density:

Density can be defined as property that links mass of an object to its volume.  It derived quantity and its unit is gml-1 for liquids and gcm-3 for solid.  The density of material can be calculated with the help of formula,

Density=Mass(g)Volume(mlorcm3)

Explanation

When sugar is excreted, the total mass will be increased due to the mass of water and sugar in the urine.  When the water is excreted, there is no drastic change in the mass...
