Question

what is pressure........​

Answer 1

Answer:

♦️I hope it helps you♦️

Pressure, in the physical sciences, the perpendicular force per unit area, or the stress at a point within a confined fluid. The pressure exerted on a floor by a 42-pound box the bottom of which has an area of 84 square inches is equal to the force divided by the area over which it is exerted; i.e., it is one-half pound per square inch. The weight of the atmosphere pushing down on each unit area of Earth’s surface constitutes atmospheric pressure, which at sea level is about 15 pounds per square inch. In SI units, pressure is measured in pascals; one pascal equals one newton per square metre. Atmospheric pressure is close to 100,000 pascals.

Pressure is defined to be the amount of force exerted per area. P = F A {\Large P=\dfrac{F}{A}} P=AF. So to create a large amount of pressure, you can either exert a large force or exert a force over a small area (or do both).
