Question: 131 Match List I with List II :
| List I | List II |
|---|---|
| A. Cohesion | I. More attraction in liquid phase |
| B. Adhesion | II. Mutual attraction among water molecules |
| C. Surface tension | III. Water loss in liquid phase |
| D. Guttation | IV. Attraction towards polar surfaces |
Choose the correct answer from the options given below :
(1) A-III, B-I, C-IV, D-II
(2) A-II, B-I, C-IV, D-III
(3) A-II, B-IV, C-I, D-III
(4) A-IV, B-III, C-II, D-I
Answer: Option (3)
Explanation:
Cohesion refers to the mutual attraction among water molecules due to hydrogen bonding,
so A matches with II.
Adhesion is the attraction of water molecules towards other polar surfaces,
so B matches with IV.
Surface tension is due to greater attraction among molecules in the liquid phase,
especially at the surface, so C matches with I.
Guttation is the loss of water in liquid form from the margins or tips of leaves,
so D matches with III.
Therefore, the correct matching is A-II, B-IV, C-I, D-III.
Hence, Option (3) is the correct answer.
