Term	Definition
Thermochemistry	Study of the heat effects associated with chemical reactions
Heat	Form of motion at the molecular level by which energy is transferred between materials
Calorimetry	Quantitative study of heat: the measurement of how much heat is evolved or absorbed in chemical reactions
Heat Capacity	Amount of heat needed to raise its temperature by one unit of temperature
Molar Heat Capacity	Heat capacity per mole of a substance
Specific Heat Capacity	Heat capacity per unit mass of material
Enthalpy	Amount of heat absorbed
State Property	Depends only on the state of the system and not on the path followed to reach that state
Exothermic	Reaction in which heat is evolved
Endothermic	Reaction in which heat is absorbed
Hess's Law	When several chemical equations are added or subtracted to give an overall equation, additon or subtraction of the corresponding enthalpy changes gives the enthalpy change associated with the overall equation
Standard Molar Enthalpy of Formation	Equals the enthalpy change when 1 mol of a species is formed in a standard state at a specified temperature from the most stable forms of the elements that constitute it
Bond Enthalpies	Used to estimate standard enthalpies of gas-phase reactions
Work	Increases a body's energy
Pressure-Volume Work	Expansion of a system against, or its compression by, an external pressure
1st Law of Thermodynamics	Change in internal energy of a system is the sum of the work done on it and the heat transferred to it
