Question
Which property could be used to identify a substance? A. mass B. weight C. density D. volume
Solution
The property that could be used to identify a substance is C. Density.
Here's why:
A. Mass: Mass is not unique to a specific substance. Different substances can have the same mass.
B. Weight: Weight is not a property of the substance itself, but rather a measure of the force of gravity on the substance. It can change depending on where the substance is located (for example, an object weighs less on the moon than on Earth).
C. Density: Density, which is the mass of a substance divided by its volume, is a characteristic property of a substance. This means that, at a given temperature and pressure, the density of a substance is always the same, regardless of the size of the sample. Therefore, density can be used to identify a substance.
D. Volume: Like mass, volume is not unique to a specific substance. Different substances can occupy the same volume.
