What is the reason for the decrease in viscosity as temperature rises in a liquid?

Options

  1. AMolecules lose kinetic energy
  2. BMolecules gain intermolecular forces
  3. CMolecules have low kinetic energy
  4. DMolecules can overcome intermolecular forces

Correct answer

D. Molecules can overcome intermolecular forces

Step-by-step solution

The decrease in viscosity at high temperature is due to molecules having high kinetic energy, which allows them to overcome intermolecular forces and slip past one another.
