Endothermic Process | Heat absorbing process. |
Exothermic Process | A heating dissipating process. |
Enthalpy | The amount of heat that a substance has at a given temperature and pressure. |
Heat | The energy that is transferred from one body to another because of a temperature difference. |
Heat Capacity | The quantity of heat required to change an object's temperature by exactly 1 degree of C. |
Heat of Combustion | The heat absorbed or released during a chemical reaction in which one mole of a substance is completely burned. |
Heat of Reaction | The heat released or absorbed during a chemical reaction; equivalent to H, the change in enthalpy. |
Hess's Law of Heat Summation | In going from a particular set of reactants to a particular sec of products, the enthalpy change is the same whether the reaction takes place or in a series of steps. |
Joule | The SI unit of energy; 4.184 joules equal 1.000 calorie. |

Molar Heat of Vaporation | The energy, in kilojoules, required to vaporize one mole of a liquid. |
Specific Heat Capacity | The amount of heat it takes to raise the temperature of 1g of the substance 1 degree C and is measured in J/(g x 6 degrees C) |
Standard Heat of Formation | The change in enthalpy (H) for a reaction in which one mole of a compound is formed from its constituent elements. |
Surroundings | The remainder of the universe that is outside the system. |
System | Any part of the universe that attention is focused on. |
Thermochemical Equation | A chemical equation that includes the amount of heat produced or absorbed during the reaction. |
Thermochemistry | The study of heat changes in chemical reactions. |
Universe | The totality of all existing things. |
