Answer the following question given this paragraph: 12.4 Viscosity and Laminar Flow; Poiseuille's Law Laminar flow is characterized by smooth flow of the fluid in layers that do not mix. Turbulence is characterized by eddies and swirls that mix layers of fluid together. Fluid viscosity is due to friction within a fluid. Representative values are given in Table 12.1. Viscosity has units of. Q: What property is characterized by eddies and swirls that mix layers of fluid together, unlike laminar flow? Choices: - combustion - compression - evaporation - turbulence A:
turbulence

Ques:Answer the following question given this paragraph: Nonmetals tend to gain electrons in chemical reactions and have a high attraction for electrons within a compound. The most reactive nonmetals reside in the upper right portion of the periodic table. Since the noble gases are a special group because of their lack of reactivity, the element fluorine is the most reactive nonmetal. It is not found in nature as a free element. Fluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances. Q: What elements have the highest attraction for electrons? Choices: - gases - metals - carbons - nonmetals A:

Ans:nonmetals
