Why is friction greater in water?
A gas like air, is marked by lower density of molecules than a solid or liquid. Friction is caused by molecules bumping into eachother, so the more molecules there are to run into, the higher the friction. So, air has less molecules per cubic foot and therefore has less density and less friction than water.
Can a liquid experience friction?
As liquid flows on an inclined surface there will be frictional force between the bottom most layer and the surface of inclined plane. More over there will be a friction between the successive layer of the liquid. This is termed as viscous force.
The kind of friction that exists between oil and a door hinge?
i am sure that it is liquid friction trust me i am a science teacher
What do you call a force that opposes the motion of one surface as it moves across another?
This is one form of the property called friction. It is not a kinetic force, but opposes a force. It is caused by the interaction between molecules of the interacting surfaces. When motion occurs between surfaces, friction may convert mechanical energy to thermal energy (heating).For some surfaces, notably liquids, it can be much less than others, notably rough solids. There are different types of friction, and rolling friction is usually less than sliding friction. Lubricants are used to reduce friction by adding a layer of smoother or liquid material between surfaces.
Examples of the 3 types of friction?
air friction also called air resistance or drag solid friction which is just normal friction and liquid friction like hydro-dynamics
What fluid force opposes motion?
Both the friction between the moving body and the liquid, and between the molecules of the liquid. And other intermolecular forces the keep the liquid together (like Van-der-Waal force)

What is the difference between the molecules in a hot solid and hot liquid?
The molecules in a solid vibrate in place. The molecules of a liquid are moving about.
What is the attraction between water molecules and the molecules of solid surfaces called?
Adhesive forces is the attraction between a solid and liquid surface. The difference in strength is determined by the behavior of a liquid coming in contact with a solid.
What property of liquids is affected by the strength of the attraction between the molecules?
Viscosity --The resistance of a liquid to flow is called its viscosity
What is between the molecules of liquid water?
Water molecules are linked by hydrogen bonds.

As liquid flows on an inclined surface there will be frictional force between the bottom most layer and the surface of inclined plane. More over there will be a friction between the successive layer of the liquid. This is termed as viscous force.
Why do some liquids have greater viscosity than others?
Viscosity is determined by the internal friction between the molecules of a liquid. Factors such as molecular size and shape, intermolecular forces, and temperature influence viscosity. Liquids with larger and more complex molecules, stronger intermolecular forces, and lower temperatures tend to have greater viscosity because the molecules have a harder time sliding past one another.
How does the attraction between molecules affect the ability of a liquid to flow?
Attractions between molecules may affect the viscosity of a liquid because if the molecules aren't attracted close enough together, the viscosity will be much lower (the liquid will have a watery appearance). If the molecules are closer together, the liquid will have a higher viscosity
In steam are the forces between molecules the same as the forces between the molecules in water?
No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.
