Specific gravity of a liquid is defined as its density relative to

  • A.water at a stated temperature
  • B.air taken at the very same conditions
  • C.mercury held at zero degrees Celsius
  • D.the same substance in its solid state

Answer: A

The reference must be stated because water itself changes density with temperature, and a value quoted without it is ambiguous. For gases the reference is air rather than water. Density itself carries units while specific gravity does not.
