1.The density of water = 1.0 g/ml, gycerol = 1.26 g/ml , and oil = 0.9 g/ml. These density are similar. However, their ranking for flow rate is different. Why their flow rate is different?
You can explain it like this-
Explain using the particle theory. Particle theory states all matter is made up with tiny particles.
answer the question no 1 or answer it by using the particle theory.
Please help me.

The more detailed answer is that the viscosity is controlled by intermolecular forces. This is where the particle theory comes in to play.
Very weak intermolecular forces, with little attraction among particles, are easy to pull apart. Therefore they have a low viscosity and will flow quickly.
The opposite is true for strong intermolecular forces.

They flow differently because their viscosities are different.
From the perspective of particles, the molecules of each of these compounds sticks to each other to different degrees. The more they "stick" together, the more resistance they will give to their volume changing shape, a requirement of flowing.

something to do with viscosity maybe
