Samples of aluminum, copper, and silver at room temperature that each weigh 1 kg are heated. The specific heat of these metals are 0.233 J/g°C (silver), 0.387 J/g°C (copper), and 0.895 J/g°C (aluminum). If the same amount of heat energy is added to each substance, which metal will show the greatest increase in temperature? A. Silver
B. Copper
C. Aluminum

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
