Which of the following is incorrect statement for liquid?

Options

  1. ASurface tension of a liquid decreases with increase in temperature
  2. BViscosity of a liquid decreases with decrease in temperature
  3. CVapour pressure of a liquid increases with increase in temperature
  4. DDroplets of a liquid on flat surface are slightly flattened due to gravity

Correct answer

B. Viscosity of a liquid decreases with decrease in temperature

Step-by-step solution

Viscosity of a liquid increases with decrease in temperature as kinetic energy of the molecules decreases and hence, intermolecular attraction increases which in turn increases the viscosity of a liquid.
