Understanding Viscosity in Gases and Liquids
Viscosity is a measure of a fluid's resistance to flow. It is influenced by temperature, and its behavior varies between gases and liquids.
1. Viscosity of Gases
- The viscosity of a gas increases with an increase in temperature.
- As temperature rises, gas molecules gain kinetic energy, leading to more frequent and intense collisions.
- This increased molecular activity results in a higher resistance to flow, hence a higher viscosity.
2. Viscosity of Liquids
- The viscosity of liquids behaves differently, typically decreasing with rising temperature.
- As temperature increases, the liquid molecules gain energy, which reduces the intermolecular forces holding them together.
- This reduction in cohesive forces allows the liquid to flow more freely, thus decreasing its viscosity.
Conclusion
Both statements correctly describe the behavior of viscosity in gases and liquids:
- Statement 1 is accurate: Viscosity of a gas increases with temperature.
- Statement 2 is also accurate: Viscosity of a liquid decreases with temperature.
Thus, the correct answer is option 'C', as both statements are correct. Understanding these principles is crucial for applications in various fields, including physics, engineering, and chemistry.
