Term
|
Definition
| term that explains how much heat is contained in a substance |
|
|
Term
|
Definition
| the Celsius absolute scale(absolute temperature scale measured in degrees Celsius) |
|
|
Term
|
Definition
| the Fahrenheit absolute scale (absolute temperature scale measured in degrees Fahrenheit) |
|
|
Term
|
Definition
| heat transfer from one molecule to another (i.e. heat traveling through metal) |
|
|
Term
|
Definition
| heat transfer moves heat from one place to another through fluid medium such as air or water |
|
|
Term
|
Definition
| when a change of temperature can be registered |
|
|
Term
|
Definition
| "hidden heat" when heat (BTU's) has been added but there is no rise in temperature |
|
|
Term
|
Definition
| a unit less number because it is the density of a substance divided by the density of water (sink or float) The more dense an item is the more likely it is to sink. |
|
|
Term
|
Definition
| the amount of heat necessary to raise the temperature of 1 pound of a substance 1 degree Fahrenheit |
|
|
Term
|
Definition
| compares the volume that each pound of gas occupies (how light or heavy gases are under the same circumstances) |
|
|
Term
|
Definition
when pressure is applied to a contained
volume of air the volume will become smaller and the pressure becomes greater |
|
|
Term
|
Definition
| If the volume is constant (not changing) then pressure is reacting to absolute temperature BUT if pressure is constant then volume is reacting to absolute temperature. |

Term
| General Law of Perfect Gas |
|
Definition
| A combination of Boyle's law and Charles' law. It includes volume, temperature and pressure. |
|
|
Term
|
Definition
| The total pressure of a contained mixture of gases is the total amount of each different pressure of each different kind of gas. |
