Which statements accurately describe volume? Check all that apply. 1. Volume is a physical property of an object. 2. Volume is measured using a balance. 3. The volume of a solid changes with the shape of the container. 4. One unit of volume is the milliliter. 5. Liquids and solids have constant volume.
The Correct Answer and Explanation is:
The correct statements are:
✅ 1. Volume is a physical property of an object.
✅ 4. One unit of volume is the milliliter.
✅ 5. Liquids and solids have constant volume.
Explanation:
Volume is a measure of the amount of space an object or substance occupies. It is one of the physical properties of matter, along with mass, density, and temperature. A physical property is a characteristic that can be observed or measured without changing the identity of the substance. Therefore, statement 1 is correct—volume is indeed a physical property.
Statement 2 is incorrect because volume is not measured using a balance. A balance is used to measure mass, not volume. Volume is measured with different tools depending on the state of matter. For liquids, graduated cylinders or measuring cups are commonly used. For regularly shaped solids, you can calculate volume using mathematical formulas (e.g., volume of a cube = side³), and for irregular solids, water displacement methods are often used.
Statement 3 is also incorrect because the volume of a solid does not change based on the shape of the container it is placed in. Solids have a definite shape and volume, which means they do not conform to the shape of the container. Liquids, on the other hand, take the shape of their container, but they still have a constant volume, unless affected by changes in temperature or pressure.
Statement 4 is correct because the milliliter (mL) is a standard unit of volume in the metric system. One milliliter is equivalent to one cubic centimeter (1 mL = 1 cm³).
Finally, statement 5 is correct because solids and liquids typically have a constant volume. Unlike gases, which expand to fill their containers, solids and liquids maintain their volume unless acted upon by external forces like heat or pressure.
In summary, statements 1, 4, and 5 correctly describe the concept of volume.
