Question

Arrange the following steps in proper sequence to determine the relative density of liquid by using a constant immersion hydrometer.
(a) The test tube is made to float in the given liquid.
(b) The weight of the test tube with lead shots in air is determined `(W_(1))`.
( c) The depth of the test tube immersed in water (h) is determined.
(d) The test tube is made to float in water.
(e ) Lead shots are added or removed from the test tube such that the test tube is immersed to the same depth (h) in the given liquid.
(f) The relative density of the liquid is measured as `(W_(1))/(W_(1))`.
(g) The test tube is taken out from the given liquid and its weight `(W_(2))` is measured.

Answer 1

Correct Answer - A
(a) The weight of the test tube with lead shots in air `(W_(1))` is measured.
(b) The test tube is made to float in water.
(c ) The depth of the test tube immersed in water (h) is determined.
(d) The test tube is made to float in the given liquid.
(e ) Lead shots are added or removed from the test tube so that the test tube is immersed to the same depth (h) in the given liquid.
(f) The test tube is taken out from the liquid and its weight `(W_(2))` is measured.
(g) The relative density of the liquid is measured as `(W_(2))/(W_(1))`.
