Suppose 2.00 mol of an ideal, monatomic gas is initially at a pressure of 3.00 atm and a temperature t 350 k. it is expanded irreversibly and adiabatically (q 0) against a constant external pressure of 1.00 atm until the volume has doubled. (a) calculate the nal volume. (b) calculate w, q, and u for this process, in joules. (c) calculate the nal temperature of the gas.

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /

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.
