Coefficient of viscosity of a gas a)increases with increase of tempera...
Explanation:
Viscosity of a gas:
- Viscosity is a measure of a fluid's resistance to deformation.
- In gases, viscosity arises from the random translational motion of the gas molecules.
- The coefficient of viscosity of a gas is influenced by factors such as temperature and pressure.
Effect of temperature on viscosity:
- The coefficient of viscosity of a gas increases with an increase in temperature.
- When the temperature of a gas increases, the average speed of the gas molecules also increases.
- The increased molecular speed leads to more frequent and stronger collisions between molecules.
- These collisions result in a higher resistance to flow, thus increasing the viscosity of the gas.
Explanation of the correct answer:
- When the temperature of a gas is increased, the viscosity also increases due to the higher molecular speeds and increased molecular collisions.
- Therefore, option 'A' is the correct answer as the coefficient of viscosity of a gas indeed increases with an increase in temperature.
Conclusion:
- The coefficient of viscosity of a gas is directly related to temperature, with an increase in temperature leading to an increase in viscosity.
- Understanding this relationship is important in various applications involving gases, such as in the design of industrial processes and equipment.
