exothermic

Question 9

heat is absorbed

Answer 9

endothermic

Question 10

Answer 10

Exothermic

Question 11

exothermic-organize

Answer 11

condensation
freezing
deposition

Question 12

endothermic

Answer 12

Melting
Sublimation
Evaporization

Question 13

Exothermic -Highest release of heat

Answer 13

Deposition

Question 14

Δ heat lost or gained in the conversion involving solid and
liquid by 1 mole of substance

Answer 14

Molar Heat of Fusion (ΔHfusion)

Question 15

s–l melting/fusion

Answer 15

heat is absorbed therefore +ΔHfusion

Question 16

l—s (freezing/congealing)

Answer 16

heat is lost therefore -ΔHfusion

Question 17

Δ required for the conversion involving liquid and gas by 1
mole of liquid substance.

Answer 17

Molar Heat of Vaporization (ΔHvaporization)

Question 18

L → G (vaporization)

Answer 18

Heat is absorbed therefore (+) ΔHvap

Question 19

G → L (condensation)

Answer 19

Heat is lost or release therefore (-) ΔHvap

Question 20

Graphs that relate pressure and temperature to the state of matter.

A visual picture of the existence and extent of the presence of solid and

liquid phases in binary, ternary, and other mixtures.

Also known as temperature-composition diagram
