Question

precautions when using a density bottle

Answer 1

Explanation:

(i) The density bottle must be held by the neck to avoid expansion.

(ii). The outside must be wiped clean.

(iii). Ensure that there is no air bubble in the bottle.

Answer 2

Precautions while using a density bottle are:

• A density bottle is a bottle whose volume is known its empty weight is measured and then weighted containing liquid whose density needs to be determined.

• Precaution that should be taken while measuring the density using the density bottle is that it should be carefully handled by holding the bottle by its neck to avoid expansion.

• The glass bottle with which the density is to be determined should be completely dry from the inside as well as outside.

• The glass density bottle should have contained any kind of bubbles in it. Since the bottle has a fixed and known volume presence of any kind of bubble in it may cause a change in its volume leading to an error in the density calculation of the desired sample.
