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
Both statement-I and statement-II are correct.
Both statement-I and statement-II are not correct.
Statement-I is correct but statement-II is not correct.
Statement-I is not correct but statement-II is correct.
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 $\mathrm{kg} \mathrm{m}^{-1} \mathrm{~s}^{-1}$.
