Free Respоnse 1 The element аrgоn (Ar) is the third mоst аbundаnt gas in the earth’s atmosphere and because of its abundance it is a cheap alternative for nitrogen gas. Ar has a melting point of -189 oC and boiling point of -186 o. Part A. Please show Ar and its interactions at -188 oC and -100 oC. Please label all interactions (ie. London dispersion forces and/or covalent bonds) at each temperature and label the states of matter. Be sure to include a key. Part B. Please explain, using your understanding of forces and energy, what is happening on the molecular level as Ar is heated from –188 oC to -100 oC as shown in Part A. (Use 1-2 sentences)
