(i) capillary tube has a large soap bubble formed at its one end and a small one at the other. Which of the two will grow at the expense of the other and why? (ii) Explain why do a large number of droplets of mercury coalesce together to form a large drop when brought in contact.
Answers
Answer:
(I)A large bubble is formed at one end of capillary tube and a small one at the other end. ... Therefore, the air will flow from smaller bubble to bigger bubble. Hence the bigger bubble will grow at the expense of smaller bubble
(ii) It is due to large cohesive force acting between the moleculeas of mercury that the droplets of mercury when brought in contact pulled together to form a bigger drop in order to make potential energy minimum. The temperature of this bigger drop icreases since the total surface area decreases
