Q: Answer the following question given this paragraph: Evaporation is a technique used to separate out homogeneous mixtures in which one or more solids are dissolved in a liquid. Typically, the mixture is heated until all of the liquid has vaporized, leaving behind the dissolved solids ( Figure below ). The vapor can also be captured and recondensed into a liquid if desired. Q: What is the term for a technique used to separate out homogeneous mixtures in which one or more solids are dissolved in a liquid? Choices: - transpiration - absorption - distillation - evaporation A:

Answer the following question given this paragraph: The metallic bonding model explains the physical properties of metals. Metals conduct electricity and heat very well because of their free-flowing electrons. As electrons enter one end of a piece of metal, an equal number of electrons flow outward from the other end. When light is shone on to the surface of a metal, its electrons absorb small amounts of energy and become excited into one of its many empty orbitals. The electrons immediately fall back down to lower energy levels and emit light. This process is responsible for the high luster of metals. Q: Why does metal conduct heat and electricity so well? Choices: - electromagnetism - free flowing photons - insulation - free flowing electrons A:
**Answer**
free flowing electrons
