The specific gravity of mercury is 13.6. The specific weight of mercury is <\/p>\n\n\n\n
(a) 1.36 kN\/m3 <\/p>\n\n\n\n
(b) 9.81 kN\/m3 <\/p>\n\n\n\n
(c) 106 kN\/m3 <\/p>\n\n\n\n
(d) 133 kN\/m3 <\/p>\n\n\n\n
(e) 13,600 kN\/m3<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n The correct answer is (d) 133 kN\/m\u00b3<\/strong>.<\/p>\n\n\n\n Specific gravity is a dimensionless quantity that relates the density of a substance to the density of water. For mercury, the specific gravity is given as 13.6, meaning mercury is 13.6 times denser than water.<\/p>\n\n\n\n The specific weight (also called weight density) is a measure of the weight of a material per unit volume. It is related to the density (mass per unit volume) of the substance by the following formula:<\/p>\n\n\n\n [ Where:<\/p>\n\n\n\n The specific weight of mercury is 133 kN\/m\u00b3, which is derived from its density and the acceleration due to gravity.<\/p>\n","protected":false},"excerpt":{"rendered":" The specific gravity of mercury is 13.6.
