27
Kinetic description of liquids
- touching - ability to flow - little expansion - permeability
28
What is cohesion?
attraction between the same substance
29
What is adhesion?
attraction between different substances
30
What are the 3 cohesive effects?
1. surface tension 2. surfactant 3. viscosity
31
What is surface tension?
the tightening of the surface due to unbalanced inter forces
32
What is a surfactant?
detergent; reduces the surface tension; mixing of polar and nonpolar
33
What is viscosity?
the thickness of a liquid; resists flowing
34
What are the 5 adhesive effects?
1. meniscus 2. capillary action 3. diffusibility 4. permeability 5. wetness
35
What is meniscus?
the curved upper surface
36
What is capillary action?
attraction of the molecules of the glass tube
37
What is diffusibility?
drop of food color diffuses through water
38
What is permeability?
permeates through
39
What is wetness?
attraction of liquid to the surface
40
What is vaporization?
l to g
41
What is evaporation?
l to g; at the surface; at all temps; cooling process
42
What is boiling?
l to g; at a specific temp; throughout
43
What is vapor pressure?
due to evaporated molecules above a liquid
44
What is boiling point?
temp where vapor pressure equals the applied pressure
45
What is normal boiling point?
the temp at which the vapor pressure equals 760 torr
46
What is distillation?
the process of separating; each substance is called a fraction
47
What is a phase diagram?
shows the pressure and temp at the phases
48
What is the triple point?
the pressure and temp at which all 3 happen at the same time
49
What is critical temp?
the highest temp at which a g can be liquified
50
What is critical pressure?
the pressure required to liquify a g at its critical temp
