What is pressure?
Step 1 of 3
Pressure is a force exerted by the substance per unit area on another substance. Pressure is the push (or force) exerted per unit area by gaseous molecules as they collide with the surfaces around them. Pressure often is expressed in units of Pascals (Pa), newtons per square meter (N/m2 or kg/m·s2), or pounds per square inch. Other units include the atmosphere (atm), torr, bar, and meters seawater (msw).
Where, P = pressure,
F = force, and
A = area
Pressure is a scalar quantity. meaning it has a magnitude, but not a direction.
