air pressure Pressure Pressure, is the ratio of a force acting on a surface, to the area of the surface; it is thus discrete from the total force acting on a surface. Units of draw are force units divided by area units. Examples of these are pounds per square inch, dynes per square centimeter, or newtons (N) per square meter (Pressure n.pag). Pressure has many influences and effects on objects. When the pressure rises, it affects the melting bill and the stewing point of a substance. This causes the raising of the melting and boiling points of most substances (Pressure The... n.pag).
Pressure can be seen and demonstrated in many ways; including air pressure, Bernoullis principle, Pascals Principle, and Archimedes Principle. Air pressure is the force exerted on you by the weightiness of tiny particles of air, called air molecules (Sample n.pag). The airs pressure is caused by the weight of air that presses down on the earth, the ocean, and the air (Understanding....If you urgency to get a full essay, order it on our website:
