physical property
Descartes had a dualist substance theory and believed that there were two substances, the mind and the body. Locke also believed that there were spiritual substances and physical substances, but his theory of substance relied on the substratum, a characterless thing that contains the characteristics we observe. Since we cannot observe substance, Locke believed we could not know anything about it.
Observe is a verb.
what
Earth Day is not a federal holiday so states are not required to observe this day. Many states have certain things they do during the day. Most other countries do not observe Earth Day.

chemical properties can be observed only when the substances in a sample of matter are changing into different substances
A property, or maybe something specifically, an empirical
A characteristic of something you are able to observe is that you are actually able to see it. It is also imperative that you would be able to notice changes in its appearance or behavior.
rate of erosion
When you can observe something's characteristics, they are called physical traits. These are the things you can see, hear, smell.
Yes. Specifically, the sense of touch.
without changing the object
Some characteristics that can be observed or measured without changing the identity of the matter include color, density, melting point, boiling point, odor, and conductivity. These properties help identify and classify different substances without altering their composition.
You need to observe at least two sets of properties to classify a material as a heterogeneous mixture. This is because a heterogeneous mixture is a combination of different substances that can be distinguished by their properties, such as size, color, and phase. By observing multiple sets of properties, you can confirm that the mixture is not uniform in composition.
Yes, you can use your senses to observe properties of a substance. For example, you can use sight to observe its color and texture, smell to detect any odors, touch to feel its texture and temperature, and taste to determine its flavor.
You would do that to observe the result of changing it.
