Signature Δ PE gravity = mg Δ h ; Δ E bond = Δ H Δ m ; Δ E thermal = mc Δ T ; 1000 g = 1 kg; 1 J = 1 Nm = 1 kg m 2 /s 2 Winter 2007 1. The atom-atom potential for a particular element, designated A , is shown to the right. The atoms of a second element, designated B , have atom-atom spacing similar to that of element A . The heat of vaporization of element B is about twice that of element A . Sketch the atom-atom potential acting between two atoms of element B on the same graph to the right, taking care to appropriately scale the graph with respect to the graph of the atom- atom potential acting between the atoms of element A. Explain in a few sentences why you drew the graph the way you did. 2. A monatomic substance is simulated with 100 atoms on the computer program Atoms-In-Motion (the one used in DL). You see that it is in its solid phase and that the temperature is above 0 K.
