With the increase in temperature, the viscosity of a liquid:
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Remain same
- D. None
Explanation
This is the correct answer. An increase in temperature causes the molecules in a liquid to gain more kinetic energy and move more rapidly. This increased molecular motion disrupts the attractive forces between molecules, reducing the resistance to flow, and thereby decreasing viscosity.

About Physics of Solids
Solids are compared through crystal structure, amorphous arrangement, elasticity, plastic deformation, stress, strain and Young’s modulus. Electrical behavior depends on available charge carriers and band structure, so conductors, insulators and semiconductors must be distinguished from mechanical properties such as strength, stiffness and brittleness.
