MCQ
For which of the two pairs, the angle of contact is same
- AWater and glass; glass and mercury
- ✓Pure water and glass; glass and alcohol
- CSilver and water; mercury and glass
- DSilver and chromium; water and chromium
✓
Answer
Correct option: B.
Pure water and glass; glass and alcohol
b
(b)Both liquids water and alcohol have same nature (i.e. wet the solid). Hence angle of contact for both is acute.
(b)Both liquids water and alcohol have same nature (i.e. wet the solid). Hence angle of contact for both is acute.
