States of matter

States of matter refer to the different forms that matter can exist in - solid, liquid, and gas. When describing the color, size, shape, or smell of an object, you are providing characteristics that are related to its physical appearance rather than its state of matter. Therefore, the correct answer is not option B, but rather option A - physical properties of matter.

Physical properties of matter

Physical properties of matter are characteristics that can be observed or measured without changing the substance's chemical composition. They describe the external attributes of an object and include properties such as color, size, shape, texture, mass, density, odor, and temperature. These properties can help identify and classify different substances.

Color
Color is a physical property that describes the visual appearance of an object. It refers to the specific wavelengths of light that are reflected or absorbed by the object. For example, an apple may appear red, while a lemon appears yellow.

Size
Size is another physical property that refers to the dimensions or magnitude of an object. It can be described using measurements such as length, width, and height. For instance, a small pebble may have a different size compared to a large rock.

Shape
Shape is a physical property that describes the form or outline of an object. It can be described using terms such as round, square, rectangular, or irregular. Different objects can have various shapes, such as a circular plate or a triangular pyramid.

Smell
Smell or odor is a physical property associated with the perception of certain substances through the sense of smell. It relates to the chemical compounds present in an object that can be detected by the olfactory system. For example, a rose may have a pleasant fragrance, while vinegar has a strong, pungent odor.

Therefore, when describing the color, size, shape, or smell of an object, you are providing information about its physical properties rather than the states of matter.
