Answer 2

Pressure :

Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.

Formula :

P = F/A

where , P = pressure

F = Force

A = Area

Additional Information :

1) 4 different types of pressure :

1. Absolute pressure.
2. Atmospheric pressure.
3. Differential pressure.
4. Overpressure (gauge pressure) .

2 ) Vacuum is an air pressure measurement that is less than Earth's atmospheric pressure, about 14.7 psi. A perfect vacuum, by definition, is a space where all matter has been removed.
