Solution
To answer the question step by step:
-
Understanding the context: The question is about the effect of increasing temperature on the motion of particles in a liquid that is below its boiling point.
-
Basic principles:
- Temperature is a measure of the average kinetic energy of the particles in a substance.
- As temperature increases, the kinetic energy of the particles also increases.
-
Effect on particle motion:
- When the temperature of a liquid increases, the particles gain more kinetic energy.
- This increased kinetic energy causes the particles to move faster.
-
Analyzing the options:
- Option A: "The motion of the particles strengthens the forces between the particles." This is incorrect because increasing temperature generally weakens intermolecular forces as particles move faster and further apart.
- Option B: "The particles move faster." This is correct because increased temperature results in increased kinetic energy, causing particles to move faster.
- Option C: "The particles move slower." This is incorrect because increasing temperature causes particles to move faster, not slower.
- Option D: "The motion of the particles overcomes the forces holding the particles together." This is partially correct but more relevant to the boiling point where particles have enough energy to break free from the liquid phase into the gas phase.
-
Conclusion: The correct answer is B. The particles move faster.

Assertion: The viscosity of liquid increases with rise of temperature.Reason: Viscosity of liquid is the property of the liquid by virtue of which it opposes the relative motion amongst its different layers.
