For most liquids, viscosity increases with increasing:

  1. Pressure
  2. Temperature
  3. Surface tension

   Select the correct option from codes given below:

Answer: [A] 1 & 3 Only

In liquids main cause of viscosity is cohesion between the molecules. As the temperature of a liquid increases, its surface tension decreases.The viscosity of liquids reduce with increase in temperature.
