What best describes the temperature at which a solid turns into a liquid? melting point boiling point electrical conductivity thermal conductivity

Melting point

Explanation:

Melting point is the temperature at which solid state gets converted to liquid state.

Boiling point is the temperature at which vapor pressure of the liquid becomes equal to atmospheric pressure. It is the temperature at which liquid state gets converted to gaseous state.

Electrical conductivity is the property of a material that characterizes a material how easily it can conduct electricity.

Thermal conductivity is the property of a material that characterizes a material how easily it can conduct heat.

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
