Pressure Quiz

Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.

Gauge pressure is the pressure relative to the ambient pressure.

Some units used to express pressure include the pascal (Pa), pound-force per square inch (psi), atmosphere (atm), torr, centimetre of water, millimetre of mercury, and inch of mercury.
