Chapter 10 Flashcards
1
Q
Properties of Gases
A
- assume the shape and volume of its container
- can be compressed
- have lower densities
- form homogenous mixtures
- described by volume, amount, temp, pressure
2
Q
Kinetic Theory of Gases
A
- gas composed of large number of particles that seem like round objects that move in constant motion
- move in straight lines until they collide with another particle or the walls of a container
3
Q
Pressure
A
force applied per unit area
= Force/Area
4
Q
Boyle’s Law
A
P1V1 = P2V2
- used only at constant T and n
5
Q
Charles’s Law
A
V1/T1 = V2/T2
- used only with constant P and n
6
Q
Avogadro’s Law
A
1 mol (g) = 22.4 L
- used only with STP (1 atm and 0 deg C)
7
Q
Ideal Gas Law
A
PV = nRT
- R = gas constant = 0.08206 L x atm/mol x K
8
Q
What happens to the pressure if the volume of a container is decreased?
A
increased; P (proportionate) 1/v
9
Q
What happens to the pressure if we increase the temperature inside the container?
A
increased; P (proportionate) T
10
Q
STP
A
1 atm and 0 degrees C
11
Q
Avogadros number
A
6.0221e23
12
Q
Ideal gas laws assume
A
- no attractions between gas molecules
- gas molecules do not take up space
