Problem Analysis:
The task involves completing math sentences related to the
phases of matter using words from a provided word bank. The goal is to understand how matter changes between different states (solid, liquid, gas) and match these changes with the appropriate terms.
#### Word Bank:
- heat
- gas
- solid
- liquid
- sublimes
#### Phases of Matter:
1.
Solid: A state where particles are closely packed and have fixed positions.
2.
Liquid: A state where particles are close but can move past each other.
3.
Gas: A state where particles are far apart and move freely.
4.
Sublimation: The process where a solid directly changes into a gas without becoming a liquid.
#### Task Breakdown:
We need to fill in the blanks for two scenarios:
1. When a
solid changes to a
liquid.
2. When a
liquid changes to a
gas.
---
Solution:
#### 1. When a solid changes to a liquid:
- A solid becomes a liquid through a process called
melting.
- Melting occurs when
heat is added to the solid, causing its particles to gain enough energy to break free from their fixed positions and move more freely.
- The resulting state is a
liquid.
Thus, the math sentence is:
$$
\text{solid} + \text{heat} = \text{liquid}
$$
#### 2. When a liquid changes to a gas:
- A liquid becomes a gas through a process called
vaporization or
evaporation.
- Vaporization occurs when
heat is added to the liquid, causing its particles to gain enough energy to overcome the forces holding them together and escape into the gaseous state.
- The resulting state is a
gas.
Thus, the math sentence is:
$$
\text{liquid} + \text{heat} = \text{gas}
$$

Final Answer:
$$
\boxed{
\begin{aligned}
1. & \quad \text{solid} + \text{heat} = \text{liquid} \\
2. & \quad \text{liquid} + \text{heat} = \text{gas}
\end{aligned}
}
$$

Explanation:
-
Heat is the key factor in both processes, as it provides the energy needed for particles to change their state.
- The transitions are based on the fundamental principles of thermodynamics and the behavior of matter under different energy conditions.
