What does the term 'density' refer to in the context of matter?

Back

Density is the mass of a substance divided by its volume, often expressed in grams per cubic centimeter (g/cm³). It determines whether an object will float or sink in a fluid.

How does taste qualify as a physical property of matter?

Back

Taste is considered a physical property because it can be observed and described without altering the chemical composition of the substance.

What happens to objects that are less dense than water when placed in it?

Back

Objects that are less dense than water will float when placed in water.

Can odor be classified as a physical property? Why or why not?

Back

Yes, odor is classified as a physical property because it can be detected and described without changing the substance's chemical identity.

What is the difference between physical properties and chemical properties?

Back

Physical properties can be observed without changing the substance's identity, while chemical properties describe how a substance reacts with other substances, resulting in a change in composition.

How can size be considered a physical property?

Back

Size is a physical property because it can be measured and observed without altering the substance's chemical structure.

What role do physical properties play in the identification of substances?

Back

Physical properties are used to identify substances because each substance has unique characteristics that can be measured and compared.
