Oxygen and Chlorine are among the gaseous elements in the periodic table. Determine the temperature when the root-mean-square speed of chlorine molecules is the same as the root-mean-square speed of oxygen molecules at room temperature (25.0°C). Hint: The molar mass of O2 is 32.00 g/mol; Cl2 is 70.90 g/mol.
