Question

Quizplus · Accepted Answer

The mercury barometer readings do not need to be corrected for the moisture content of the air. The other factors listed do affect the measurements, and corrections need to be made to obtain accurate readings. Temperature affects the volume of the mercury column, changes in the acceleration of gravity with latitude affect the weight of the column, and elevation above sea level affects the air pressure.
