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.)
