Explanation:
Atmospheric pressure is defined as the force per unit area exerted against a surface by the weight of the air molecules above that surface. ... The pressure applied by this air on the unit area would be 14.7 pounds per square inch. Meteorologists use a metric unit for pressure called a millibar.
Step By Step Solution Liquids don't have any specific shape and so every molecule in the liquid wants to be in a low energy state which is achieved when it lies flat on any surface with the gravity acting perpendicularly and so when you place the liquid in a container then the liquid tries to go in low energy ...
The instrument used to measure liquid pressure is called manometer.
The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m2, or kg·m−1·s−2). Pascal is a so-called coherent derived unit in the SI with a special name and symbol.
The force is exerted by electrostatic charge or electrically charged object is called electrostatic force.
Gravitational force -an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.
