(a)
Interpretation:
The compound having the higher surface tension is to be stated.
Concept introduction:
The surface tension is the property of liquid due to the balanced force of attractions of the molecules at surface due to which they are pushed inward. The molecule the surface of liquid resists moving due to this tension. The surface tension of the liquid is directly proportional to the force of attractions among the molecules of the liquid.
(b)
Interpretation:
The compound having the higher surface tension is to be stated.
Concept introduction:
The surface tension is the property of liquid defined as the resistance to flow. The surface tension of the liquid is directly proportional to the force of attractions among the molecules of the liquid. It also depends upon the shape and size of the molecule.
