Air pressure is measured by a barometer. One type of barometer utilizes an evacuated, calibrated tube inverted in a pool of mercury that is open to the atmosphere. As air pressure increases, the mercury will rise in the column until the weight of the mercury in the column equals the force exerted by the air on the surface of the pool. The barometer shown here (Figure 1) measures atmospheric pressure in millimeters of mercury (mmHg ). According to this barometer,...

Gases are different from solids and liquids. In a sample of gas, the molecules are far apart. The gas molecules also move around and collide with each other as well as with the walls of the container. These collisions generate pressure. The pressure of a gas can be measured in different units. One convenient unit of measure is called the atmosphere (atm) because it is based on atmospheric pressure. At sea level, the average pressure is 1 atm. As you...
