Question

Ethanol flows faster than honey. 

1. Name the related phenomenon.

 2. Explain this phenomenon. 

3. What is the effect of temperature on this?

Answer 1

1. Viscosity. 

2. Viscosity is a measure of resistance to ow which arises due to the internal friction between layers of fluid as they slip past one another while liquid flows. 

3. Viscosity of liquids decreases as the temperature rises because at high temperature molecules have high kinetic energy and can overcome the intermolecular forces to slip past one another between the layers.
