Zaniyah Townsend · Answer 1

Answer: Thus A glass of lemonade at room temperature will have lowest viscosity

Explanation:

Viscosity is defined as the resistance to the flow of a fluid.

The lesser are the inter molecular forces between the particles of a liquid, the lesser will be the viscosity and thus it will flow rapidly. More are the inter molecular forces between the particles of a liquid, the more the viscosity of the liquid and thus it will flow slowly.

Viscosity decreases with increase in temperature as the forces among particles decrease due to increase in kinetic energy and thus they offer less resistance to flow.

Thus A glass of lemonade at room temperature will have lowest viscosity

Zachery Meza · Answer 2

Option D

Explanation:

The viscosity of all the given liquids is as follows -

a) Pancake syrup at room temperature - 5000 centipoise

b) Motor oil that is in the refrigerator - 85-140 centipoise

c) Liquid mercury at room temperature - 1.526 centipoise

d) A glass of lemonade at room temperature - 1-3 centipoise

Thus the lowest viscosity is of lemonade at room temperature.

Option D is correct
