Investigation 2.1

The unit of measurement for air pressure.

• bar

• isobar

• millibar (mb)

• density

A weather tool that measures air pressure.

• isobar

• atmospheric pressure

• barometer

• equilibrium

The amount of mass in a sample of matter compared to the volume of that sample.

• kinetic energy

• bar

• density

• millibar

The force exerted on a surface by the mass of the air above it.

• kinetic energy

• barometer

• atmospheric pressure

• equilibrium

The unit that meteorologists use when reporting air pressure on a weather map.

• isobar

• barometer

• millibar

Smooth, non-intersecting lines on a map that represent air pressure over a large region.

• kinetic energy

• atmospheric pressure

• density

• isobar

When air is compressed, the pressure decreases.

• True

• False

Air particles are always moving, giving them kinetic energy.

• True

• False
