Question

The thin-walled tube of a thermometer weighs 66 g-wt in air with the mercury inside. Its weight in water is 44 g-wt. Find the weight of the mercury in the tube. The specific gravity of mercury is 13-6 and that of glass is 2.6.

Answer 1

Answer: P ≅ 10^-9 g-wt.

Explanation:

where P_1, P₂ are the respective weights of the thermometer in air and in water, and y₀ , y_1,  y₂ are the specific gravities of water, mercury, and glass.
