Properties of Liquid and Solid

Question 1

liquid due to intermolecular forces exhibit:

Answer 1

• vapor pressure and boiling point
• evaporation
• capillarity
• viscosity
• surface tension

Question 2

• the ability of a fluid to resist flowing
• can be measured using a viscometer
• polar molecules and molecules with complex structure tend to have higher viscosity

Answer 2

viscosity

Question 3

• the force that causes the molecules on the surface of a liquid to “tighten their hold to one another” creating the effect of a thin membrane on the surface
• temperature dependent; it decreases as temperature increases

Answer 3

surface tension

Question 4

• the spontaneous rising of a liquid in a narrow tube

Answer 4

capillarity

Question 5

the escape of molecules from the surface of the liquid

Answer 5

evaporation

Question 6

the tendency of a material to change into the gaseous or vapor state, and it increases with temperature.

Answer 6

vapor pressure

Question 7

the temperature at which the vapor pressure of a liquid equals the pressure sorrounding the liquid and the liquid changes into a vapor

Answer 7

boiling point

Question 8

other properties:

Answer 8

• incompressibility
• volatility

Question 9

the property of being incompressible

Answer 9

incompressibility

Question 10

the ability of a substance to vaporize

Answer 10

volatility

Question 11

the temperature at which a solid melts

Answer 11

melting point

Question 12

the amount of heat required to completely melt a solid

Answer 12

heat of fusion

Question 13

the change from solid to gas w out passing through the liquid state

Answer 13
