Given below are two statements. Statement I: Viscosity of liquid decreases with increase in temperature. Statement II: The units of viscosity are kg m ⁻¹ ~s ⁻² . The correct answer is

Options

  1. ABoth statement-I and statement-II are correct
  2. BBoth statement-I and statement-II are not correct
  3. CStatement-I is correct but statement-I is not correct
  4. DStatement-I is not correct but statement-II is correct

Correct answer

C. Statement-I is correct but statement-I is not correct

Step-by-step solution

Viscosity depends strongly on temperature in liquids it usually decrease with increasing temperature because temperature increase 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 .
