What is characteristic property of a substance?
The characteristic properties of a substance are always the same whether the sample one is observing is large or small.
What properties does not change?
Properties that do not change are known as intrinsic properties, which include characteristics such as mass, density, and chemical composition. These properties remain consistent regardless of the sample's size or the conditions it is subjected to. For instance, water will always have a specific chemical formula (H2O) and a characteristic density at a given temperature and pressure. Other examples include boiling point and melting point, which are inherent to the substance itself.
What is a charateristic poperty?
A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample you are observing is large or small. Examples of characteristic properties include freezing/melting point, boiling/condensing point, density, magnetism, and solubility.
What changes did you observe in the iron sample during the reaction?
During the reaction, the iron sample underwent noticeable changes such as a color shift, often turning from metallic gray to a reddish-brown due to the formation of iron oxide (rust). Additionally, there may have been a change in texture, with the iron becoming more brittle and flaky as it reacted with oxygen and moisture. Overall, the sample's physical properties were altered, indicating a chemical transformation.
What happens to a fixed sample of gas when its temperature changes?
When the temperature of a fixed sample of gas changes, its particles will gain or lose kinetic energy, leading to a change in their speed and collisions. This results in a change in pressure and volume of the gas, according to the ideal gas law.
Can characteristic properties will change if you have a different amount of a sample.?
This depends for intensive (not dependent of mass) and extensive (dependent of mass) properties.
Why volume and mass are not charestic properties of matter?
Volume and mass are not characteristic properties of matter because they can change based on external conditions, such as temperature and pressure. Characteristic properties are those that remain constant and unique to a specific substance regardless of the amount or sample size, such as density or boiling point.
Kelly has a sample of an unknown substance. Which properties of the substance will be the same no matter how large or small her sample is?
The chemical composition and intrinsic properties, such as density, melting point, boiling point, and specific heat capacity, will remain the same regardless of the sample size. These properties are characteristic of the substance itself and do not change with the amount of the sample.
What is characteristic property of a substance?
The characteristic properties of a substance are always the same whether the sample one is observing is large or small.
How does properties can be observed only when the substances in a sample of matter are changing into different substances?
Properties can be observed when a substance undergoes a chemical change, resulting in the formation of new substances with different properties. These properties can include changes in color, odor, temperature, and the formation of new substances. By observing these changes, we can identify and characterize the original substances based on their unique properties.
Is it true or false that characteristic properties of elements do not depend on the amount of material present in a sample of the element?
True. Characteristic properties of elements, such as melting point, boiling point, density, and chemical reactivity, do not depend on the amount of material present in a sample of the element. These properties are unique to each element and remain constant regardless of the quantity of the substance.

Sample sentence for the word particular?
We shall discuss changes in properties selected for their particular interest.
Is a sample a number describing some characteristic of a statistic?
No. A statistic is a number describing a characteristic of a sample.
How will identifying if a property is chemical or physical?
A physical property can be observed without changing the sample. Chemical properties requires you to change the sample.
Is hardness extensive or intensive?
No matter what size a sample is, if is hard, it will still be just as hard. This means that hardness is an intensive properties. Intensive properties do not matter what size of sample is being used. Extensive properties will change if sample size is changed.
