Answer :
To determine which statement most accurately describes the properties of the substances in the given table, let's analyze each substance based on their recorded properties:
1. Leonna's substance:
- Definite shape? Yes (X)
- Definite volume? Yes (X)
Having both a definite shape and a definite volume means that Leonna's substance is a solid.
2. Xiao's substance:
- Definite shape? No
- Definite volume? Yes (X)
Having no definite shape but a definite volume means that Xiao's substance is a liquid.
3. Blake's substance:
- Definite shape? Yes (X)
- Definite volume? No
Having a definite shape but no definite volume does not correspond to any known state of matter, indicating that Blake may have made a mistake in recording or interpreting the properties of the substance.
4. Amir's substance:
- Definite shape? No
- Definite volume? No
Having neither a definite shape nor a definite volume means that Amir's substance is a gas.
Now, let's review the given statements and match them with our analysis:
1. Leonna has a solid, Xiao and Blake have liquids, and Amir has a gas.
- This statement is incorrect because Blake's substance does not fit any known state of matter.
2. Leonna and Amir have gases, Xiao has a liquid, and Blake has a solid.
- This statement is incorrect because Leonna's substance is a solid, not a gas.
3. Leonna has a solid, Xiao has a liquid, Blake has a gas, and Amir made a mistake.
- This statement is incorrect because Blake's substance does not fit the properties of a gas.
4. Leonna has a solid, Xiao has a liquid, Blake made a mistake, and Amir has a gas.
- This statement is correct based on the properties we analyzed.
Therefore, the correct and most descriptive statement is:
Leonna has a solid, Xiao has a liquid, Blake made a mistake, and Amir has a gas.
Hence, the correct answer is 4.
1. Leonna's substance:
- Definite shape? Yes (X)

- Definite volume? No
Having a definite shape but no definite volume does not correspond to any known state of matter, indicating that Blake may have made a mistake in recording or interpreting the properties of the substance.
4. Amir's substance:
- Definite shape? No
- Definite volume? No
Having neither a definite shape nor a definite volume means that Amir's substance is a gas.
Now, let's review the given statements and match them with our analysis:
1. Leonna has a solid, Xiao and Blake have liquids, and Amir has a gas.
- This statement is incorrect because Blake's substance does not fit any known state of matter.
2. Leonna and Amir have gases, Xiao has a liquid, and Blake has a solid.
- This statement is incorrect because Leonna's substance is a solid, not a gas.
3. Leonna has a solid, Xiao has a liquid, Blake has a gas, and Amir made a mistake.
- This statement is incorrect because Blake's substance does not fit the properties of a gas.
4. Leonna has a solid, Xiao has a liquid, Blake made a mistake, and Amir has a gas.
- This statement is correct based on the properties we analyzed.
Therefore, the correct and most descriptive statement is:
Leonna has a solid, Xiao has a liquid, Blake made a mistake, and Amir has a gas.
Hence, the correct answer is 4.
