Temperature
The ideal gas law states that pressure and ___ are directly related
Pressure
If the temperature decreases so does the ___ (Ideal Gas Law)
Volume
In nature we don't see the temperature go to extremes when above sea level (low pressure) and below sea level (high pressure). This is due to the countering effect of ___ changing
Pressure
If a volume of a gas is allowed to expand and contract when the ___ changes, this will counter the changes in temperature.
