Definition
| amount of force exerted per unit area; SI unit is the pascal. |
|
|
Term
|
Definition
| explanation of the behavior of molecules in matter; states that all matter is made of constantly moving particles that collide without losing energy. |

|
Term
|
Definition
- states that pressure applied to a fluid is transmitted throughout the fluid.
|
|
|
Term
|

Term
|
Definition
- increase in the size of a substance when the temperature is increased.
|
|
|
Term
|
Definition
| states that the volume of a gas increases with increasing temperature as long as the pressure is held constant |
|
|
Term
|
Definition
one of the three states of matter where the particles are moving more freely, possessing enough kinetic energy to slip out of an ordered arrangement; no definite shape (takes the shape of its container) and definite volume.
|
|
|
Term
|
Definition
| states that if you decreases the volume of a container of gas and hold the temperature constant, the pressure of the gas will increase |
