The specific gravity of lipid is _______

  • A.1.0
  • B.1.5
  • C.0.5
  • D.0.8

Answer: D

The specific gravity of lipid is 0.8.

Fats and oils are lighter than water, with specific gravities a little below 1, typically about 0.8 to 0.9. That is why oil floats on water and why fat separates as a layer on top of milk.

1.0 is the specific gravity of water itself, and 1.5 would make lipids sink. 0.5 is far too low for fats and oils, so of the options, 0.8 is the value the key accepts.
