Answer 1

Explanation:

Density bottle is a small glass bottle which has a glass stopper at its neck. The bottle can store a fixed volume of a liquid. Generally, the density bottle comes in two sizes, 25ml or 50ml. The glass stopper has a narrow hole in it. When the bottle is filled with liquid and a stopper is inserted. The excess liquid rises through the hole and drains out. Thus the bottle will contain the same volume of liquid each time when it is filled. It is used to determine the density of a liquid.
