Pressure is the force per unit
newton
What is the SI unit of force?
pressure
What does the constant bombardment of gas molecules against the inside walls of a container produce?
barometer
What instrument measures atmospheric pressure?
745 torr.
A pressure of 745 mm Hg equals
570 mm Hg
Convert the pressure 0.75 atm to mm Hg.
638 mm Hg
Convert the pressure 0.840 atm to mm Hg.
253 kPa
Convert the pressure 2.50 atm to kPa.
0°C
Standard temperature is exactly
760 mm Hg
Standard pressure is the pressure exerted by a column of mercury exactly
1 atm
Standard pressure is exactly
Pressure
Temperature

Amount
What is the 4 variables you must have values for, in working gas law problems?
Pressure
PSI
Temperature
Standard for this – 0 Celsius
Volume
mL, cm3, cubic inches can be used to measure this
Moles (amount)
n
The expression V= kn is a statement of
22.4 L
The standard molar volume of a gas at STP is
The ideal gas law combines Boyle’s law, Charles’s law, Gay-Lussac’s law and
P = nRTV
All of the following equations are statements if the ideal gas law except:
P = nRTV
P/n = RT/V
PV/T = nR
R = PV/nT
R = 0.0821 L*atm / K* mole
R = 62.4 L*torr. / K* mole
R equals
