|
|
Term
|
Definition
| the atoms in matter are in a constant state of motion. |
|
|
Term
|
Definition
| Gas and liquids states of matter move around freely |
|
|
Term
|
Definition
| characterized by a definite volume and a definite shape |
|
|
Term
|
Definition
| is a fluid whose volume is fixed under conditions of constant temperature and pressure |
|
|
Term
|
Definition
| they have the ability to flow and do not resist deformation, do not occupy a fixed volume, but instead expand to fill whatever space they occupy. |
|
|
Term
|
Definition
| is the result of the impulses that result from the collision of molecules with the walls of their containers. |
|
|
Term
|
Definition
| states that the volume of a fixed amount of gas varies inversely with the pressure of gas. If volume decreases, the no. of particle collisions icrease, and pressure will icrease, and vice versa |
|
|
Term
|
Definition
| Defines the relationship between temperature and volume of gas. The volume of a fixed gas varies with temperature of gas. If temp. increases, volume increases. |
|
|
Term

|
|
Term
|
Definition
| is a form of energy that causes the particles of matter to move faster and farther apart. |
|
|
Term
|
Definition
| refers to the physical change of a substance from one state to another. ex. ice melting |
|
|
Term
|
Definition
| heat energy needed per unit mass to change the phase of a substance. |

Term
|
Definition
| a temperature scale on which water freezes at 0° and boils at 100° |
|
|
Term
|
Definition
| Temperature scale based on 32F for the temperature at which water freezes and 212F for the temperature at which water boils Conversion to Farhenheit from Celsius temperature scale is by the following formula: F = 9/5C + 32. |
