VERSION | 100% VERIFIED
gas pressure is caused by... - (answer)the force exerted by gas molecules colliding with the
surfaces of objects
atmospheric pressure is caused by... - (answer)the weight of the column of air molecules in the
atmosphere above an object
pressure - (answer)the force exerted on a given area
P=F/A
unit= Pascal
pascal (Pa) - (answer)1 Pa = I N/m^2
atmosphere (atm) - (answer)I atm = 101,325 Pa
kilopascal (kPa) - (answer)1 kPa = 1000 Pa
pounds per square inch (psi) - (answer)air pressure at sea level is 14.7 psi
bar (b) - (answer)1 bar = 100,000 Pa
millibar (mb) - (answer)1000 mb = 1 b
inches of mercury (in Hg) - (answer)1 in Hg = 3386 Pa
, torr - (answer)760 torr = 1 atm
millimeters of mercury (mmHg) - (answer)1 mm Hg = 1 torr
barometer - (answer)a glass tube that is closed at one end, filled with a non-volatile liquid,
inverted, and then immersed in a container of that liquid
- the atmosphere exerts pressure on the liquid outside the tube, the weight of the column of liquid
exerts pressure inside the tube and the pressure at the liquid surface is the same inside and
outside the tube
- height of liquid in tube is proportional to the pressure exerted by the atmosphere
Increased Temperature = - (answer)Increased Pressure
Decreased Temperature = - (answer)Decreased Pressure
Amonton's Law (P-T relationship for gases) - (answer)The pressure of a given amount of gas is
directly proportional to its temperature on the kelvin scale when the volume is held constant
P1/T1 = P2/T2
Increased Temperature = - (answer)Increased volume
Decreased Temperature = - (answer)Decreased volume
Charles Law - (answer)the volume of a given amount of gas is directly proportional to its
temperature on the kelvin scale when the pressure is held constant
