Q: On increasing the temperature of a liquid, the viscosity of the liquid ______?
  • A. Decrease
  • B. Increase
  • C. First decrease and then increase
  • D. Remains same
Correct Answer: Option A - When two adjacent layers of fluid are in relative motion, then they resist the motion of each other, such the fundamental property of fluid is known as viscosity. When the temperature of liquid is increases the viscosity of liquid will be decreases due to the intermolecular force of attraction decrease.
