Suppose 12.0g of oxygen (O2) gas is heated at constant atmospheric pressure from 25.0oC to 125oC.
(a) How many moles of oxygen are present? (See Table 19-1, for the molar mass.)
(b) How much energy is transferred to the oxygen as heat? (The molecules rotate but do not oscillate.)
(c) What fraction of the heat is used to raise the internal energy of the oxygen?
