Question:
When the temperature is raised, the viscosity of liquid decreases. This is because
When the temperature is raised, the viscosity of liquid decreases. This is because
Show Hint
Viscosity of liquids decreases with temperature due to weakened intermolecular forces.

- decreased volume of the solution
- increased attraction between molecules
- decreased covalent and hydrogen bond forces
- increase in temperature increases the average kinetic energy of molecules which overcomes the attractive force between them
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Increase in temperature increases molecular kinetic energy.
Step 2: Intermolecular attractions are overcome.
Step 3: Hence viscosity decreases.
