List gas characterisitcs
|
~ compressible
~ pressure, temp, volume, & molar amount relate |
|
|
What does the ideal gas law allow us to relate?
|
temp, pressure, volume, and molar amount
|
|
|
Pressure
|
the force exerted per unit area of surface
|
|
|
acceleration
|
chnge in speed per unit time
|
|
|
SI unit of pressure
|
kg/(ms^2)
|
|
|
Pascal
|
SI unit of pressure kg/ms2
|
|
|
Barometer
|
device - measures pressure of atmosphere
|
|
|
sea level ATM measurement
|
760 mmHg (torr)
|
|
|
manotmeter
|
device - measures pressure of gas/liquid in a vessel
|
|
|
Evangelista Torricelli
|
invented the Hg barometer in 1643
|
|
|
mmHg (torr)
|
pressure equal to that exerted by 1 mm high column of Hg at 0.0 oC
|
|
|
relationship between pressure & height of Hg in barometer/manometer
|
P = gdh (g=gravity constant, h = height, d = density of liquid)
|
|
|
Charles Boyle
|
in 1661 found that adding Hg to a closed J-tube would compress the gas on the other end
|
|
|
Boyle's Law
|
volume of gas @ certain temp varies INVERSELY with the pressure on it
|
|
|
Boyle's Law in an equatin
|
PV = constant (4 given amount of gas @ fixed temp.)
