Term
What does NOT happen as a result of pressure and temperature's linear relation? |
|
Definition
There may be negative pressures once you reach a certain negative temperature. Instead, there is absolute zero at 0 on the Kelvin scale. |
|
|
Term
How must temperature always be expressed in gas laws? |
|
Definition
|
|
Term
Why are volume and temperature inversely related? |
|
Definition
As temperature increases, gas particles move faster and have harder collisions, thus causing the need for the volume to expand if pressure is to remain constant. |
