1.	What do you mean by the statement 'the atmosphericpressure is 1 atm. State its value in pascal.
Answer» <p>Atm (short for atmosphere) is a unit of pressure. It is defined to be equal to the pressure at sea level in the internationally accepted standard atmosphere model. It is equal to a pressure of 101,325 N/m^2 = 101,325 Pa = 1.01325 bar = 1013.25 mbar = 1013.25 hPa = 14.6959 psi = 29.9213 inches of mercury</p><p>If the air pressure happens to be equal to 1 atm, then it means that it happens to be equal to the specific pressure we have agreed to use as the standard pressure at sea level. The real pressure in the air varies, so it’s hardly ever that the pressure would beexactlyequal to 1 atm.</p>
