Liquids

Question 1

Properties of liquids

Answer 1

Vapor pressure
Surface tension
Viscosity

Question 2

Property that depends on temperature and nature of liquid

Answer 2

Vapor pressure
temp up, vapor pressure up
IMFA up, vapor pressure down

Note. Incredible strength of IMFA
LDF, Dipole dipole, H-bonding

Question 3

Resistance to motion of a fluid

Answer 3

Viscosity

Question 4

Property dependent on nature of liquid, temperature, and pressure

Answer 4

Viscosity.
For liquids
Temp up, viscosity down
Pressure no effect
IMFA up, viscosity up

For gases
Temp up, viscosity up
Pressure up viscosity up

Question 5

____ experimentally measures the viscosity of liquids

Answer 5

Viscometer

Question 6

Ability of liquid surface to behave like a thin, stretched membrane.

Answer 6

Surface tension

Question 7

Property that depends on nature of substance, temperature, ressure, and added solute

Answer 7

Surface tension
IMFA up, surface tension up
Temp up, surface tension down
Added solute up, surface tension down

Question 8

Methods used in determining surface tension

Answer 8

Capillary rise method (gradient)
Bubble method (differential pressure)
Drop weight method (measuring weight and dimension of drop)

Question 9

Equation that relates surface tension with temp.

Answer 9

Katayama equation

Question 10

Relates surface tension with concentration of added solute

Answer 10

Gibbs isotherm
