This is a multi-faceted question. In biological terms, fluids flow across selectively permeable membranes due to concentration gradients. The fluid will flow to the side witht he greater solute concentration (or osmolarity).

What causes friction between fluids and how does it affect the flow of the fluids?

Friction between fluids is caused by the interaction of molecules within the fluid. This friction can slow down the flow of the fluids, making it more difficult for them to move smoothly. It can also create turbulence and resistance, which can further impede the flow of the fluids.


What force causes the bulk flow of fluids?

Pressure Gradient


What force causes the bulk flow of fluids (gases and liquids) in a system?

The force that causes the bulk flow of fluids in a system is typically pressure difference. This pressure difference drives the movement of fluids, such as gases and liquids, from areas of high pressure to areas of low pressure.


How do fluids move through a pressure difference?

Fluids flow from areas of high pressure to areas of low pressure.


Why are gases and liquids reffered to as fluids?

because they move with a flow. liquid flow down the ground, gases flow in currents


Why solids are not called fluids?

Solids are not called fluids because solids have a fixed shape and volume, while fluids can change shape and flow to fill the container they are in. Solids have particles that are tightly packed together and vibrate in place, whereas fluids have particles that are able to move past each other.


Why does fluid flow?

Fluids flow due to the presence of a pressure difference, which causes them to move from areas of high pressure to areas of low pressure. This movement is governed by the laws of physics that describe how fluids behave under different conditions. Factors such as viscosity, density, and the geometry of the system also influence the flow of fluids.


Which state of matter has the ability to flow?

Fluids have the ability to flow. Fluids are Liquids and Gasses.


Why do very viscous fluids tend to be difficult to pour or flow easily?

Viscous fluids are difficult to pour or flow easily because they have high resistance to deformation and flow. This resistance is due to the strong intermolecular forces present in viscous fluids, which make it harder for the molecules to move past each other. As a result, viscous fluids flow slowly and require more force to pour compared to less viscous fluids.


Why liquidgas or plasma considered fluids?

Fluids are substances that flow. Liquids flow, gases flow, and ionized gases (plasmas) flow. Thus, they are all fluids.


Fluids like air tend to move toward areas of high pressure?

Yes, fluid flow (such as air) follows the principle of pressure differentials, moving from areas of high pressure to low pressure to achieve equilibrium. This movement is what causes wind, as air flows from high to low pressure systems. Fluids will continue to move until pressure is balanced across all regions.


What are characteristics of viscosity?

Viscosity is the measure of a fluid's resistance to flow. Fluids with high viscosity flow slowly, while fluids with low viscosity flow quickly. Viscosity is influenced by factors such as temperature, pressure, and molecular structure of the fluid.
