This is because the surface is more even and equal. For example if you have a wooden surface and a glass surface, the wooden surface would have more friction than the glass, because it is more un-even than the glass surface
Because a smooth surface minimizes the amount of rubbing against it by another object by making it slide just as a wet surface might do. A wet surface also has slightly scattered molecules, preventing too much fruction on one spot
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
wet surfaces like tiles have the least amount oof friction
becuase it does
This type of friction is called lubricated friction. Lubricated friction is a type of fluid friction where a fluid separates two solid surfaces.
Friction is reduced on a wet floor.

Colder temperatures can cause friction on surfaces to decrease as it can make surfaces more smooth and slippery. Rain or wet conditions can also reduce friction due to the presence of moisture on the surface. Additionally, icy or frosty conditions can lead to a decrease in friction as the ice or frost can create a slippery surface.
when we polish surfaces, the molecules or atoms of surface come closer to each other so there is no space for fiction so it is reduced but not reduced to zerowe cant reduce friction to zeroWhen we polish a rough surface smoothly,the unequalities gets reduced,therefore friction is reduced
Driving on smooth wet surfaces is dangerous.

Smooth surfaces are surfaces that have less contact with things touching them and thus have less friction. Less friction means there are fewer contact points to stop your motion. Think of it like this: you are climbing a tree. You grab the next branch. Which is more likely to hold you in place (stopping your motion down), one finger or four? More contact points, meaning more fingers and more friction, means you it is more difficult for gravity (or any other force) to pull you down. In the same way, more contact points because of more friction, such as sand paper, is held in place more firmly. As for water, it acts as a lubricant which causes less friction by stopping the points of contact from actually touching.
As the bathroom becomes wet the friction between the floor and leg becomes less.
Friction is reduced on a wet floor.
yes cement road surfaces are more slippery when wet then asfault yes the worst would be if it is covered by a film of liquid sufficient enough to reduce the coefficient ecstatic friction between the tyre and the road to essentially zero, but not so deep as to introduce a new source of friction
All physical substances so far known have a coefficient of friction. In the cases of some substances (wet ice or teflon, for example) this may be quite low, but there are no truly frictionless surfaces.
