Effects of temperature on viscosity of liquid and gases

  • The viscosity of a liquid or gas is directly influenced by temperature. 
  • When the temperature of a liquid increases, its viscosity decreases. This means that the liquid becomes less resistant to flow and can flow more easily. 
  • Conversely, when the temperature of a liquid decreases, its viscosity increases, making it more resistant to flow. 
  • For gases, the relationship between temperature and viscosity is more complex. 
  • Generally, when the temperature of a gas increases, its viscosity decreases, making it more likely to flow. 
  • However, the relationship between temperature and viscosity for gases is not as strong as for liquids. 
  • It's important to note that the specific effect of temperature on the viscosity of a liquid or gas can vary depending on the material and its properties.
