What happens to the viscosity of a liquid when its temperature increases?
What happens to the viscosity of a liquid when its temperature increases?
- Viscosity decreases because particles move faster and farther apart. (correct)
- Viscosity increases due to greater particle attraction.
- Viscosity stays the same regardless of temperature changes.
- Viscosity fluctuates randomly without a clear trend.

Study Notes
States of Matter
-
Fluid: Anything that flows (liquid or gas). Examples include water, syrup, and compressed air.
-
Solids: Have a definite shape and volume. Particles are close together and vibrate in place.
-
Liquids: Have an indefinite shape but a definite volume. Particles are close together but can flow.
-
Gases: Have an indefinite shape and volume. Particles are distant and move randomly.
Changes of State
- Evaporation: Liquid to gas.
- Condensation: Gas to liquid.
- Melting: Solid to liquid.
- Solidification: Liquid to solid.
- Sublimation: Solid to gas.
- Deposition: Gas to solid.
Particle Theory of Matter
- All matter is made of tiny particles.
- Particles in a pure substance are identical. Different substances have different particles.
- There is space between particles.
- Particles are always moving. Their speed increases as they gain energy.
- Particles attract each other. The strength of attraction depends on the type of particle.
Viscosity
- Viscosity is a liquid's resistance to flow (thickness or thinness).
- Greater friction between particles means higher viscosity.
- Flow rate is the time it takes a fluid to flow from one point to another (distance/time).
Factors Affecting Viscosity
- Temperature: Higher temperature reduces viscosity as particles move faster and farther apart.
- Concentration: Increased concentration leads to higher viscosity as there are more particles in a given space.
- Strength of attraction: Stronger attractions between particles lead to higher viscosity.
