The value V in the bent tube is initially kept closed. Two soap bubbles A (smaller) and B (larger) are formed at the two open ends of the tube. V is now opened, and air can flow freely between the bubbles.

Tow soap bubbles A and B are formed at the two open ends of a tube. The bubble A is smaller then bubble B. If the valve on the tube connecting the two bubbles is opened and air can flow freely between the bubbles, then

Two soap bubbles are formed on the end of the ends of the tubes as shown. If valve is opened, in which direction will the air flow ?

A and B are two soap bubbles. Bubble A is larger than B. If these are now joined by a tube then

The soap bubble formed at the end of the tube is blown very slowly. Draw the graph between excess of pressure inside the bubble with time.

Two soap bubbles of unequal sizes are blown at the end of a capillary tube. Which one will grow at the expense of the other end what does it show?

In the figure, the cross-sectional area of the smaller tube is a and that of the larger tube is 2a . A block of mass m is kept in the smaller tube having the base area that of the tube. The difference between water levels of the two tubes is

Two soap bubbles A and B of different diameters are blown at the two ends of a bent tube. By opening the stopcock S , the two bubbles are put in communication. What will happen?

Two vessels A and B of equal volume (V_0) are connected by a narrow tube which can be closed by a value. The vessels are fitted with piston which can be moved to change the volumes. Initially, the valve is open and the vessels contain an ideal gas (C_p / C_v = gamma ) at atomspheric pressures (P_0) and atmoshpeheric temperature (T_0) . The walls of the vessels A are diathermic and those of B are adiabatic. The value is now closed and the pistons are slowly pulled out to increase the volumes of the of the vessels to dobuled the original value.(a) Find the temperatures and pressures in the two vessels. (b) The value is now opened for sufficeint time so that the gases acquire a common tempertures and pressures . Find the new values of the temperatuere and the pressures.
