Which statements about matter are correct? A) All matter can be seen. B) Matter has mass and volume. C) Solid, liquid and gas are states of matter. D) The different states of matter have the same properties.

What you are checking in these statements

You need to decide which statements match the scientific definition of matter and how the states of matter behave.

Evaluate each statement

• A: “All matter can be seen.” False. Many types of matter are invisible, such as air or water vapor.
• B: “Matter has mass and volume.” True. This is the standard definition: matter has mass and takes up space.
• C: “Solid, liquid and gas are states of matter.” True. These are the three common states taught in basic science.
• D: “The different states of matter have the same properties.” False. States differ in properties such as shape and volume:
• solids have a fixed shape and volume
• liquids have a fixed volume but change shape
• gases change both shape and volume

Match to the answer choices

Only B and C are correct, so the correct option is (2).
