Statement (A): When the temperature increases the viscosity of gases increases and the viscosity of liquids decreases. Statement (B): Water does not wet an oily glass because cohesive force of oil is less than that of water. Statement (C) : A liquid will wet a surface of a solid if the angle of contact is greater than .
- A A. B. and C are false
- B A and B false,
C is true - C B and C false, A is true
- D A and C false, B is true
Answer & Solution
Correct Answer
(C) B and C false, A is true
Step-by-step Solution
Detailed explanation
Statement A: In liquid: With the rise in temperature, viscosity of a liquid decreases because the intermolecular attractive force between consecutive layers decreases as temperature increases. In gasses: The important cause of viscosity is randomness/molecular collision due to…
