| A | B |
|---|
| Thermochemistry | Study of the changes in heat in chemical reactions |
| Exothermic reactions | Reactions that release heat |
| Endothermic reactions | Reactions that absorb heat |
| Enthalpy change | When the pressure remains constant, the heat absorbed or released during a chemical reaction is equal to the enthalpy change for the reaction |
| Standard Enthalpy change | An enthalpy change that is measured when reactants in their standard states change to products in their standard states |
| Hess's Law | If a series of reactions are added together, the enthalpy change for the net reaction will be the sum of the enthalpy changes for the individual steps |
| Calorimetry | The study of heat flow and heat measurement |
| Heat capacity | The amount of heat needed to raise the temperature of the object by 1 Celcius degree |
| Specific heat | The heat capacity of 1 gram of a substance |
| Kinetic theory | Heat results from the motion and vibration of particles of matter |
