Two statements are given below. Statement I: Viscosity of liquid decreases with increase in temperature. Statement II: The units of viscosity coefficient are Pascal sec. The correct answer is
Options
- ABoth statement-I and statement-II are correct.
- BBoth statement-I and statement-II are not correct.
- CStatement-I is correct but statement-II is not correct.
- DStatement-I is not correct but statement-II is correct.
Correct answer
A. Both statement-I and statement-II are correct.
Step-by-step solution
Viscosity depends strongly on temperature in liquids it usually decreases with increasing temperature because temperature increases the kinetic energy of the molecule as a result the molecule overcomes the intermolecular attractive force between them. Units of viscosity is pascal-second or kg m ⁻¹ ~s ⁻¹ .
