Answer 1

6. A thermometer that uses elemental bromine instead of alcohol would have some advantages and disadvantages. On the positive side, bromine has a higher boiling point than alcohol, which means the thermometer would be able to measure higher temperatures. Additionally, bromine is a nonmetal and has a lower density than alcohol, which could make it easier to read the thermometer. However, there are also some potential hazards associated with using bromine in a thermometer. Bromine is a toxic substance and can cause burns upon contact with skin or inhalation of its vapors. Additionally, bromine is a flammable liquid, which could pose a fire hazard if the thermometer were to be exposed to high temperatures or flames. Overall, while a bromine-based thermometer may have some useful properties, the potential hazards associated with bromine make it a less ideal choice than an alcohol-based thermometer.7. In general, nonmetals have lower densities than metals. This can be seen in Figure 2, where the density values for nonmetals are lower than those for metals.8. There are several similarities and differences between the data of metals and nonmetals in Figure 1 and Figure 2. Some similarities include the fact that both metals and nonmetals have a range of melting and boiling points, and that both have a range of densities. However, there are also some key differences between the two groups. For example, metals generally have higher melting and boiling points than nonmetals, and they also have higher densities. Additionally, metals are good conductors of heat and electricity, while nonmetals are generally poor conductors.
