Surface Tension Quiz for Students

A square frame of side I is dipped in liquid soap. When it is taken out of the liquid a film is formed on it. If the surface tension is T then the force acting on it is :

A rectangular frame of thin wire of length 4 cm and breadth 3 cm just rests on the surface of the water of surface tension 72 dyne/cm. The force due to surface tension acting on the frame is

A soap film is formed on a rectangular frame of a length of 7 cm and breadth of 3 cm dipping in a soap solution. The framework hangs from a balance and an extra weight of 0.4 g is placed in the opposite pan to balance the pull of the film. The surface tension of the soap solution is (g= 1000 cm/s²) :

Insects can move on the surface of the water without sinking due to :

Surface tension is the force per unit length on an imaginary line at the surface of liquid directed :

The surface tension of boiling water is :

The light thread is loosely bound along the diameter of the metal ring. If the metal ring is dipped in soap solution and taken out. The thread rests in a zigzag way. If the film on the right side is pricked with a pin. Then the thread :
