Question

Answer in one word:

A special bottle used for determining the relative density of a liquid.

Answer 1

1. Specific gravity bottle or relative density bottle is used to determine the relative density of a liquid.
2. In the manner of construction, it is a small glass bottle with a glass stopper. The stopper has a fine capillary tube. It has a fixed capacity, which is usually marked on the bottle.
3. When the stopper is inserted, the excess liquid rises up and comes out through the capillary tube, which ensures the liquid is completely filled inside the bottle.

Hence, a special bottle used for determining the relative density of a liquid is a specific gravity bottle or relative density bottle.
