Unit 10 - Gases and Kinetic Molecular Theory Flashcards
1
Q
Pressure (P)
A
F/A
2
Q
What can be said about pressure if gas particles are moving fatser
A
Pressure is higher
3
Q
Temperature is
A
average energy of the particles in a system
4
Q
What is the idea gas equation
A
P = RTn/V
P = pressure R = constant T = absolute temperature (K) V = volume n = number of moles
5
Q
1 mol of gas at 1atm and at 0 deg will occupy …
A
22.4 L
6
Q
0 deg –> K
A
273K
7
Q
25 deg –>
A
298K
8
Q
1L is –>
A
1 dm3
9
Q
Pv =
A
nRT
10
Q
What does the ideal gas eqn assume
A
Molecules don’t interact or repel each other and that the molecules have inconsequential volumes
11
Q
R =
A
0.082 L atm mol-1 K-1
12
Q
1 atm —> Kpa
A
101 Kpa
13
Q
22.4 L –> m3
A
0.024
14
Q
What is dalton’s Law
A
Partial pressures all sum to give the total pressure
15
Q
What is vapour pressure
A
Partial pressure where the gaseous and liquid states are at eqbm
