Science question!!!!!!!!!!!!!! PLEASE HELP!!!!!!!!!!!!!?

Is viscosity ALWAYS related to density?

also, (this may sound kind of obvious, but I am not sure)

Are particles in dense liquids a lot closer together than those of less dense liquids?

    To answer you question, but yes particles in dense liquids are closer. Look at an ice cube, they are really close to each other, as where in steam they are far apart.

    Viscosity is a measure of the resistance of a fluid to being deformed by either shear stress or extensional stress. It is commonly perceived as "thickness", or resistance to flow. Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is "thin", having a lower viscosity, while vegetable oil is "thick" having a higher viscosity. All real fluids (except superfluids) have some resistance to stress, but a fluid which has no resistance to shear stress is known as an ideal fluid or inviscid fluid.[1] The study of viscosity is known as rheology.

    "Scientists" attack Christianity and "Christians" attack science. How can science be used to attempt non-repeatable phenomena. Did "guy" exist 7,000 years in the past? It relies upon on the variety you outline "guy." in case you outline "guy" as somebody who can record historic past, the respond must be "no." whilst i became attending college, many years in the past, C-14 relationship became reported as an "absolute" relationship technique and constrained to 50,000 years in the past. Now that is seen a relative relationship gadget. It has alway been seen as such by potential of physicists and extends previous 60,000 years. C14 is created by potential of bombarding the nitrogen loose on the remarkable of the ambience with cosmic potential. If there is far less loose nitrogen, there is far less C14 created. much less C14 in an merchandise shows an older age. science does not attack something. the 2nd it does, it ceases to be science. Scientists who take sides like which will become clergymen of "science" quite than observers of experiments and science is all approximately repeatable science. right that's the weak point of all relationship structures. no one has ever examined them for 2 hundred,000 years... or maybe 60,000 years. the concept that the forces that govern those structures are static is without data. Even the seen time has its limits. without mass/gravity, time does not exist, in accordance ot Steven Hawkings. yet, then, the Biblical relationship is likewise in step with assumptions by potential of a few nineteenth century bishop. How long is an afternoon if the earth does not rotate in terms of the solar... or if there is not any solar. Then there is the subject of randomness. If a pail of ice all of sudden began to boil, might or no longer that is a miracle or an accident of threat? science might say it became an accident of threat possibly in easy terms to take place as quickly as in one thousand billion trillion buckets of ice. quicker or later, that that's threat and that that's supernatural attain a nexus.
