Answer:
definition
Atmospheric pressure, also known as barometric pressure, is the pressure within the atmosphere of Earth. The standard atmosphere is a unit of pressure defined as 101,325 Pa, which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi.
Explanation:
formula
Pressure (p), mass (m), and the acceleration due to gravity (g), are related by P = F/A = (m*g)/A, where A is surface area. Atmospheric pressure is thus proportional to the weight per unit area of the atmospheric mass above that location.
example
When bulb is pressed, air present in tube and bulb escapes in the form of bubbles. However, there is atmospheric pressure on surface of liquid. When we release the bulb, the water moves inside the tube. Water moves from higher pressure (from water kept) to lower pressure (inside the glass tube
