Why does viscosity vary among fluids?
Imagine you are part of a small group of friends walking through a very busy Mic Mac Mall. As a small group, even if there are a lot of other people in the mall, your group can move around easily and freely as there is a lot of space between you and the other people. As you increase your group size, it becomes more and more difficult to move around the mall as the space between you decreases. So think about the particle theory. Smaller particles can move around a lot easier and faster than larger particles. This movement of particles is directly related to the fluid’s viscosity. All fluids do not flow at the same rhythm because of this. This demonstrates that particles can move around freely but encounter resistance through friction. The ability for a fluid to flow also depends on how much energy the particles have. The more a fluid is heated the more energy it has and the easier and faster it flows. As a fluid is cooled, the particles lose energy, the spaces between them decreases and
