The diagram shows a simple mercury barometer. The atmospheric pressure increases. Which distance increases?

• V W

• W Y

• X Y

• X Z

A device that is used to measure atmospheric pressure is a ___________.

• barometer
• thermometer
• kilometer
• micrometer

Explain what would happen to the column of mercury in the barometer as shown if the atmospheric pressure fell.

• As the pressure falls, the column of mercury will drop lower.
• As the pressure falls, the column of mercury will remain unchanged.
• As the pressure falls, the column of mercury will rise higher.
• As the pressure falls, the density of the mercury will increase.
