Pressure
Force per unit area
atmospheric pressure
the pressure caused by the weight of the atmosphere
Units of pressure
1 atm = 1 Pascal = 100 kPa = 760 mmHg (torrs)
STP (standard temperature and pressure)
Defined in order to compare
273 K (0 Celsius) and 1 atm
Boyle's Law
Volume and Pressure
Volume is inversely related to pressure
P1V1=P2V2
Charles' Law
volume and temperature
V1/T1=V2/T2
Kelvin scale
absolute temperature scale
C + 273
Gay-Lussac's Law
Pressure and temperature
P1/T1=P2/T2
...
(P1)(V1)/T1=(P2)(V2)/T2
Ideal Gas Law
PV=nRT
R= 0.082 L(atm)/ mol(K)
