Question
How will raise in temperature affects the viscosity of liquids and gases?Both increasesBoth decreasesIn case of liquids, decreases and in case of gases, increases.In case of liquid, increases and in case of gases, decreases.
Solution
The effect of temperature on the viscosity of liquids and gases is different.
For liquids, as the temperature increases, the viscosity decreases. This is because the increased temperature gives the molecules more energy and they move faster. This increased movement means they can slide past each other more easily, which decreases the viscosity.
For gases, as the temperature increases, the viscosity increases. This is because the increased temperature means the gas molecules are moving faster and colliding more often. These more frequent collisions increase the resistance to flow, which increases the viscosity.
So, the correct answer is "In case of liquids, decreases and in case of gases, increases."
