Dr. Mettle is trying to identify a metal that he can pour into thin cylindrical tubes. The material needs to remain in the liquid phase over a wide range of temperatures. It should melt above 30°C but not boil below 350°C. The material needs to be very heavy with a density of at least 10,000 kg/m^3. Which substance should he choose?

Respuesta :

Did you have a table of melting points and boiling points and a table of densities that went along with this question?
