As the temperature of a liquid increases, its viscosity _____. increases stays the same decreases
2 answers:
Answer: Option (c) is the correct answer.
Explanation:
Viscosity is defined as the ability of a liquid to resist its flow. When a substance has high viscosity then it is known as a viscous substance.
For example, honey has high viscosity.
But when we increase the temperature then there occurs more number of collisions between the molecules. Due to this there will be increase in kinetic energy of the molecules and they will be able to move the fluid easily.
As, Kinetic energy =
Thus, we can conclude that as the temperature of a liquid increases, its viscosity decreases.
