Question

At a certain temperature, the density of mercury is 13600 kg m–3 and its surface tension is 0.47 J m–2. Find out the work done in breaking 13.6 kg of mercury into droplets, each having a diameter or 10–6 m.

Answer 1

Answer:

A mercury drop of radius 0.5 cm falls from height on a glass plate and breaks up into a million droplets, all of the same size, Find the height from which the drop must have fallen. (Density of mercury = 13600 kg/m³, . Surface tension of mercury = 0.465 N/m) (Ans : 0.2072 m)
