Definition
| Heat is affected by mass and temperature. It has its own unique units called the joule (J) for the metric system, and calorie (cal) for the American system |
|
|
Term
| Conversion between calories and joules |
|
Definition
1 cal = 4.184 J
1000 cal = 1 Cal (when calories are written with a capitol C, it is the same as a kilocalorie or Kcal |

Term
|
Definition
| A process that results in the evolution of heat is classified as exothermic (Energy flows out of the system) |
|
|
Term
|
Definition
| A process that results in the absorbing of energy from the surroundings is classified as endothermic (Energy flows into the system |

Term
| Potential energy graphs rule #1 |
|
Definition
| The amount of energy released or gained is the difference in the potential energies between the products and the reactants |
|
|
Term
| Potential energy graphs rule #2 |
|
Definition
| If energy is released than the potential energy from the bonds is converted into kinetic energy in the form of heat |
|
|
Term
| Potential energy graphs rule #3 |
|
Definition
| If energy is gained than kinetic energy from the surroundings is converted nto potential energy in the new bonds |
|
|
Term
|

|
|
Term
|
Definition
| The energy required for the reaction to take place. The reactants must gain this energy in order for a reaction to proceed |
