|
Term
|
Definition
| when a gas or vapor becomes liquid - energy releasing process |
|
|
Term
|
Definition
| gas or vapor becomes a solid - without turning to a liquid first - energy releasing. Snowflakes and frost are water vapor that turns directly to ice |
|
|
Term
|
Definition
| chemical reaction where more energy is required to break the bonds and less energy is created when the new bonds form ** |
|
|
Term

Definition
| the amount of heat in a system at a constant pressure |
|
|
Term
|
Definition
| reaction where more energy is released than is needed to break the chemical bonds |

Term
| Law of Conservation of Energy |
|
Definition
"In any chemical or physical process - energy may change forms but it can not be created or destroyed"
PE+KE=constant |

Definition
| when a solid changes form to a liquid |
|
|
Term
|
Definition
| energy due to composition or position of an object - a book waiting to fall, or mentos waiting to have coke added |

Term
|
Definition
| amount of heat required to raise the temperature of a substance by 1 degree Celsius q=c x m x delta (change) in T (temperature) |
|
