k boiling point

1. physical state changes diagram: the following diagram represents the changes of state that can occur. label the parts of the diagram.
2. a → d
3. d → c
4. b → a
5. c → d
6. a → b
7. d → a
8. #3
9. #2
10. #1
11. definitions: match the appropriate definition with the proper physical changes.
12. boiling a. solid to a liquid
13. condensation b. solid to a gas without going through the liquid state
14. deposition c. liquid to a solid
15. evaporation d. gas to a liquid
16. freezing e. a liquid becomes a gas, occurring throughout the entire substance
17. melting f. a liquid becomes a gas, occurring only on the surface
18. sublimation g. a gas becomes a solid without going through the liquid phase

Explanation:

Step1: Classify property types

Physical Properties (P):

A. Viscosity, C. Malleability, D. Luster, E. Freezing point, G. Density, I. Conducting electricity, J. Buoyancy, K. Boiling point

Chemical Properties (C):

B. Reactivity, F. Flammability, H. Corrosive

Step2: Label state change arrows

1. $A \to D$: Vaporization (Boiling/Evaporation)
2. $D \to C$: Condensation
3. $B \to A$: Melting
4. $C \to D$: Freezing
5. $A \to B$: Fusion (Melting reverse: Freezing)
6. $D \to A$: Condensation reverse: Vaporization
7. #3: Sublimation (Solid to Gas)
8. #2: Deposition (Gas to Solid)
9. #1: Melting (Solid to Liquid)

Step3: Match definitions to changes

1. Boiling: E. A liquid becomes a gas, occurring throughout the entire substance
2. Condensation: D. Gas to a liquid
3. Deposition: G. A gas becomes a solid without going through the liquid phase
4. Evaporation: F. A liquid becomes a gas, occurring only on the surface
5. Freezing: C. Liquid to a solid
6. Melting: A. Solid to a liquid
7. Sublimation: B. Solid to a gas without going through the liquid state

Answer:

Question 4 (Property Classification):

A. Viscosity: P

E. Freezing point: P
F. Flammability: C
G. Density: P
H. Corrosive: C
I. Conducting electricity: P
J. Buoyancy: P
K. Boiling point: P

Question 5 (State Change Labels):

1. $A \to D$: Vaporization
2. $D \to C$: Condensation
3. $B \to A$: Melting
4. $C \to D$: Freezing
5. $A \to B$: Freezing
6. $D \to A$: Vaporization
7. #3: Sublimation
8. #2: Deposition
9. #1: Melting

Question 6 (Definition Matching):

1. Boiling: E. A liquid becomes a gas, occurring throughout the entire substance
2. Condensation: D. Gas to a liquid
3. Deposition: G. A gas becomes a solid without going through the liquid phase
4. Evaporation: F. A liquid becomes a gas, occurring only on the surface
5. Freezing: C. Liquid to a solid
6. Melting: A. Solid to a liquid
7. Sublimation: B. Solid to a gas without going through the liquid state
