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.
