Chapter 11 Flashcards
Gases
1
Q
Properties of Gas
A
- Gas assumes the shape and volume of the container
- Gases are compressible
- Density of gases is smaller than that of solids and liquids and depends on temperature and pressure (g/L)
- Gases form homogeneous mixtures with one another in any proportions
2
Q
Kinetic Molecular Theory
A
- Gases are composed of particles whose mass and volume are negligible and very far apart.
- Gas molecules are in constant random motion
- Gas molecules do not exert attractive/repulsive forces on each other

A
Mixing of gases
6
Q
Effusion
A
Escape of gases form a vacuum or container
7
Q
Gas Pressure Equation
A
(force)/(area)
8
Q
Pressure of Barometer Equation
A
P = hdg
(height of the column m) x (density kg/m^3) x (9.80665m/s^2)
9
Q
Boyle’s Law
A
P1V1 = P2V2
10
Q
Charles Law
