Problem Analysis:
The task involves completing sentences using terms related to the states of matter and phase changes. The provided terms are:
-
Boiling
-
Boiling Point
-
Condensation
-
Evaporation
-
Freezing
-
Melting Point
-
Sublimation
-
Vaporization
We need to match these terms with the given sentences based on their definitions and contexts.
---
Solution:
#### Sentence 1:
"The type of vaporization that takes place below the surface of a liquid is called ______."
-
Explanation: Vaporization refers to the process by which a liquid turns into a gas. There are two types of vaporization:
1.
Evaporation: This occurs when molecules at the surface of a liquid gain enough energy to escape into the gas phase.
2.
Boiling: This occurs when bubbles of vapor form within the liquid, typically at a specific temperature (boiling point).
Since the question specifies "below the surface of a liquid," the correct term is
evaporation.
-
Answer: Evaporation

#### Sentence 2:
"Liquid boils at a specific temperature called the ______."
-
Explanation: Boiling is the process where bubbles of vapor form within a liquid. This process occurs at a specific temperature for each substance, known as the
boiling point. The boiling point is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure.
-
Answer: Boiling Point
---
#### Sentence 3:
"The melting part of a substance is also the same as the ______."
-
Explanation: Melting is the process by which a solid turns into a liquid. The temperature at which this transition occurs is called the
melting point. For most substances, the melting point is the same as the freezing point (the temperature at which a liquid turns into a solid). This is because these processes are reversible and occur at the same temperature under standard conditions.
-
Answer: Freezing Point

Final Answers:
1.
Evaporation
2.
Boiling Point
3.
Freezing Point
---
Boxed Final Answer:
\[
\boxed{\text{Evaporation, Boiling Point, Freezing Point}}
\]
