States of Matter — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
Steam from a kettle is a liquid.
Corrected: Steam from a kettle is a gas.
The corrected sentence is: "Steam from a kettle is a gas.". The original sentence "Steam from a kettle is a liquid." contained an error that needed to be fixed.
2. Fix the sentence:
Juice takes a definite shape on its own.
Corrected: Juice takes the shape of its container.
The corrected sentence is: "Juice takes the shape of its container.". The original sentence "Juice takes a definite shape on its own." contained an error that needed to be fixed.
3. Fix the sentence:
A rock is a gas because it is very hard.
Corrected: A rock is a solid because it is very hard.
The corrected sentence is: "A rock is a solid because it is very hard.". The original sentence "A rock is a gas because it is very hard." contained an error that needed to be fixed.
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A liquid takes the shape of its container.
Liquids flow and take the shape of whatever container they are poured into, though they keep a fixed volume.
2. When you blow up a balloon, you fill it with gas.
Oxygen, carbon dioxide, and steam are all gases — they have no definite shape or volume.
3. Milk is an example of a liquid.
Water, juice, and milk are liquids — they flow, take the shape of their container, and have a fixed volume.
4. A desk is a solid because it has a definite shape.
Rocks and wooden blocks are solids — they have a definite shape and volume because their particles are tightly packed.
Part C: True or False?

1. You can pour a liquid from one cup to another.
True False
The statement is true based on states of matter concepts.
2. A gas has a definite shape and volume.
True False
The statement is false; review how states of matter behave.
3. A pencil is an example of a solid.
True False
The statement is true based on states of matter concepts.
