Viscous force arises from the physical interaction of a fluid medium comprised of the . Name the three states of matter. The high surface tension of water (water "sticks" to itself, so it doesn't "want to" evaporate) means water has a low vapor pressure. They differ in embryology, distribution, and function. A summary treatment of crude oil follows. 1. False; 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. . Viscosity is stronger in those substances with greater intermolecular forces because molecules cannot move around each other freely, thus hindering flow. When frozen water melts, it is undergoing a physical change. Viscosity increases with increased intermolecular force because the molecules attract each other strongly which hinders the flow. 1. Two objects can occupy the same space at the same time. 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. 1. .
