fluiditu
Fluidity refers to the ability of a substance to flow. It is a characteristic property of liquids and gases, distinguishing them from solids, which have a definite shape. The ease with which a substance flows is related to its viscosity, a measure of its internal resistance to flow. Low viscosity substances, like water, are highly fluid and flow easily, while high viscosity substances, such as honey or tar, flow more slowly.
In a fluid, particles are not held in fixed positions and can move past one another. This
