Viscosity is a measure of a fluid's resistance to flow, describing how thick or sticky a fluid is and how easily it deforms under stress. Essentially, it indicates how much internal friction a fluid has when it moves. For instance, honey has a high viscosity because it flows slowly and resists movement, while water has a low viscosity and flows easily. The concept is crucial in understanding the behavior of different liquids in various conditions, from industrial applications to everyday situations.

Temperature plays a significant role in affecting a fluid's viscosity. Generally, as temperature increases, a fluid's viscosity decreases, meaning it becomes less resistant to flow. This is why heating honey makes it flow more easily, while cooling it causes it to thicken.
