a) Exothermic: a process in which heat is transferred from the system to the surroundings. Exothermic: a process in which heat is transferred from the surroundings to the system. b) System: an arbitrarily defined portion of the universe. Surroundings: everything that's not part of the system. c) A measurement of the amount of energy that needs to be transferred as heat to raise the temperature of a unit of mass/mol by one unit of temperature. d) A property of a process whose value doesn't depend on the path chosen, only the final and initial states. e) The most stable allotrope of an atom at 1 bar pressure, in the physical state in which it exists at this pressure and room temperature. e) Energy transferred as heat to a system at constant pressure. f) The enthalpy change for the formation of one unit of mass/mol of a compound in a given physical state from the reaction of its component elements in their standard states.
