Problem Description:
The task is to identify the properties of gases and match them with the correct descriptions and images provided in the table. The goal is to check the squares that best describe the properties of gases.
Solution Approach:
1.
Understand the Properties of Gases:
- Gases have several distinct properties, including:
- No definite shape or volume.
- Expand to fill their container.
- Compressible.
- Low density.
- Exert pressure on the walls of the container.
- Diffusible (can spread out).
- Can be poured.
- Exhibits effusibility (can escape through small openings).
2.
Analyze Each Row in the Table:
- For each row, determine which description and image best align with the properties of gases.
3.
Match Descriptions and Images:
- Use the provided images as clues to identify which property they represent.
Step-by-Step Analysis:
####
Row 1:
-
Description: "has no definite shape"
- This is a property of gases.
-
Image: Balloon expanding to fill its container.
- This image represents the property of gases expanding to fill their container.
-
Check: Both "has no definite shape" and "expands to fill its container" are properties of gases. The balloon image supports the latter.
####
Row 2:
-
Description: "takes the form when they freeze"
- This is not a property of gases; it applies to solids.
-
Image: Spheres packed closely together.
- This image represents a solid state, not a gas.
-
Check: None of these apply to gases.
####
Row 3:
-
Description: "low density"
- This is a property of gases.
-
Image: Glass being squeezed into a small container.
- This image does not represent low density; it shows compression, which is also a property of gases.
-
Check: "low density" is a property of gases, but the image does not directly support it.
####
Row 4:
-
Description: "exert pressure on the walls of the container"
- This is a property of gases.
-
Image: Molecules escaping through small openings.
- This image represents effusibility, another property of gases.
-
Check: Both "exert pressure on the walls of the container" and "exhibits effusibility" are properties of gases.
####
Row 5:
-
Description: "has definite shape"
- This is not a property of gases; it applies to solids.
-
Image: Molecules spreading out.
- This image represents diffusion, a property of gases.
-
Check: "exhibits expandability" is a property of gases, and the image supports diffusion.
Final Answer:
Based on the analysis, the properties of gases and their corresponding descriptions/images are:
-
Row 1: "expands to fill its container" (balloon image)
-
Row 2: None (not applicable to gases)
-
Row 3: "low density" (no direct image match, but "squeezed into a small container" could imply compressibility)
-
Row 4: "exerts pressure on the walls of the container" and "exhibits effusibility" (molecules escaping image)
-
Row 5: "exhibits expandability" (molecules spreading out image)
Thus, the final answer is:
\boxed{
\begin{array}{|c|c|c|c|}
\hline
\text{Row 1} & \text{expands to fill its container} & \checkmark & \text{(balloon image)} \\
\hline
\text{Row 2} & \text{None} & & \\
\hline
\text{Row 3} & \text{low density} & \checkmark & \text{(indirectly supported by 'squeezed into a small container')} \\
\hline
\text{Row 4} & \text{exerts pressure on the walls of the container} & \checkmark & \\
\text{} & \text{exhibits effusibility} & \checkmark & \text{(molecules escaping image)} \\
\hline
\text{Row 5} & \text{exhibits expandability} & \checkmark & \text{(molecules spreading out image)} \\
\hline
\end{array}
}
