Polymers

QuestionAnswer
Fluids are able to flow and change shape
Sir Isaac Newton stated relationship between tempetature and the viscosity of fluids
Law of Viscosity states that only a change in temperature affects the viscosity of a fluid
viscosity liquids naturally resists flow
Newtonian fluids keep their fluid properties no matter how much they are stirred or mixed
ketchup, blood,yoguart gravy,mud,slime and pie fillings examples of non-Newtonian fluids
non-newtonian fluids may creat a hole when stirred, they are very viscous
plastic a substance that can be molded into various shapes before hardening
petroleum a form of crude oil, black gold
petroleum made from plants and animals over time with heat and pressure.
all plastics are polymers but... not all polymers are plastics
nonrenewable resource it cannot be replaced once it is used up
