Gases Flashcards
1
Q
1 atm is equivalent to:
A
101.3 kpa (kilopascals)
14.7 psi (pounds of pressure per square inch)
760 torr
760 mm Hg
29.1 in Hg
100 bar
2
Q
Ideal Gas Law and what it is used for
A
PV = nRT
Where P = pressure (ATM) V = volume (L) n = # of moles of gas K = temp R = 0.0821 (planks constants)
3
Q
To find the Molar Mass of a gas,
A
Take the g•R•T and divide by P•V
Where g is grams of substance
4
Q
Boyles Law
A
When there is a relationship between pressure and volume
P1•V1 = P2•V2
5
Q
What is pressure?
A
The force exerted on an object divided by the area over which it is exerted
6
Q
Density of a gas
A
P•V / R•T
7
Q
How many liters are there in one mole of gas?
A
22.4 liters contain one mole of gas for ANY gas
8
Q
3 variables gases are effected by
A
Volume (in liters)
Temperature (in Kelvin)
Pressure (in atmospheric pressure atm)
