Viscosity of a liquid ________ with the increase in temperature

option(1)

CONCEPT:

• Viscosity is the property of fluid by virtue of which an internal force of friction comes into play when a fluid is in motion and which opposes the relative motion between its different layers.
  • Viscosity is considered an internal resistance that comes into play when fluid is in motion.
  • The viscosity of a liquid decreases with the increase in temperature

EXPLANATION:

• Effect of temperature on viscosity: When a liquid is heated, the kinetic energy of its molecules increases and the intermolecular attraction becomes weaker. 
• Hence the viscosity of a liquid decreases with the increases in its temperature.
