Properties of Matter

Question 1

Vapor Pressure definition

Answer 1

partial pressure of gas above liquid in a closed container IN DYNAMIC EQUILIBRIUM

Question 2

2 requirements in BOILING POINTS

Answer 2

temp at liquid phase = gas phase
VP = atm

Question 3

enthalpy present in boiling point

Answer 3

enthalpy/heat of VAPORIZATION

Question 4

BOILING POINT is interchangeable with what?

Answer 4

condensation point

Question 5

enthalpy present in melting point

Answer 5

enthalpy/heat of FUSION

Question 6

MELTING POINT is interchangeable with what?

Answer 6

freezing point

Question 7

What property of liquid denotes the temperature at which the LIQUID and SOLID PHASE coexist in equilibrium

Answer 7

Melting/Freezing Point

Question 8

Viscosity DEFINITION

what does a high and low viscosity mean?

Answer 8

measure of fluid’s resistance to flow

high = malapod
low = madali

Question 9

SHORT vs LONG molecules

which of the two are more viscous?

Answer 9

LONG bc they get tangled more easily w each other

Question 10

relationship of TEMP and KE with viscosity and surface tension

and why

Answer 10

inversely

cohesive forces decrease with more KE

Question 11

SURFACE TENSION definition

Answer 11

resistance to increase surface area

Question 12

Exception to general trend in surface tension

Answer 12

Mercury - due to strong metallic bonds

Question 13

cohesive vs adhesive forces

Answer 13

c = between like
a = unlike

Question 14

2 TYPES of solids

Answer 14

crystalline
amorphous
