How would you compare physical and chemical properties and physical and chemical changes?
Physical properties are characteristics that can be observed or measured without changing the substance's identity, such as color or density. Chemical properties describe how a substance interacts with other substances, like its ability to rust or burn. Physical changes alter a substance's appearance or state without changing its chemical composition, while chemical changes result in the formation of new substances with different chemical properties.

How do the properties of substances formed in chemical changes compare to those of the original substances?
Substances formed in chemical changes have different physical and chemical properties compared to the original substances. This can include changes in color, odor, state of matter, melting/boiling points, and reactivity. The chemical composition of the new substances is also different from the original substances.
Compare and contrast how do chemical and physical properties differ?
Chemical properties describe how a substance can undergo chemical reactions to form new substances, such as flammability or reactivity. Physical properties describe characteristics that can be observed without changing the substance's identity, such as color or density. In summary, chemical properties involve changes in the composition of a substance, while physical properties refer to characteristics that do not alter the substance's chemical makeup.
Compare the total amount of energy before and after physical and chemical changes?
In physical changes, the total amount of energy before and after remains the same as no new substances are formed. In chemical changes, there may be a difference in the total amount of energy before and after the reaction due to the formation of new substances and the breaking or forming of chemical bonds.
How do the properties of a new substance compare with the properties of the original substances after a chemical change takes place?
After a chemical change, the new substance will have different properties compared to the original substances. The chemical reaction typically results in the formation of new bonds and rearrangement of atoms, leading to changes in physical and chemical properties such as color, smell, temperature, and composition. The new substance may have different reactivity, boiling point, melting point, and solubility compared to the original substances.
Compare and contrast a physical property and a chemical property?
Physical properties can be observed or measured without changing the substance's chemical composition, such as color, density, or melting point. Chemical properties describe how a substance reacts or changes into a different substance, like flammability, reactivity, or pH. In summary, physical properties describe how a substance looks or behaves under certain conditions, while chemical properties describe how a substance interacts with other substances to form new substances.

What experiment can I do that shows physical and chemical changes in fruit?
Let it rot. The physical and chemical changes are huge and can be easy shown when you compare a "good" fruit and a rotting version.
Compare and contrast chemical and physical properties?
Physical properties are characteristics of a pure substance that can be observed without changing it into another substance. Chemical properties are characteristics of a pure substance that describes its ability to change into different substance.
How do the particles that make up matter compare during physical and chemical changes?
During physical changes, the particles that make up matter remain the same and only their arrangement or state changes. In contrast, during chemical changes, the particles undergo a rearrangement or bonding at the atomic level, resulting in the formation of new substances with different properties.

How do physical and chemical properties of the halogens compare with those of the noble gases?
Noble gases are not reactiveHalogens are very reactive.
What facts about characteristic chemical and physical properties make it possible for sientist to compare and classify matter?
Scientists can compare and classify matter based on its chemical properties such as reactivity, flammability, and ability to form bonds with other substances. Physical properties such as melting point, boiling point, density, and conductivity also provide valuable information for classifying matter. By studying these properties, scientists can identify similarities and differences between different substances to categorize them accordingly.
Compare physical and chemical properties?
A chemical property is the substance's response to other substances, resulting in a new substance. A physical property is something like a substance's lustre, melting point, boiling point, colour, or density, to name a few. Examples of chemical properties are: combustibility and reaction to acid.
How do the properties of the new substance compare with the properties of the original substance after a chemical change takes place?
Mass gets preserved (you have to consider the stuff that isn't the end produced chemical, too). Otherwise, chemical changes are known for having different properties. They could have similar properties, I imagine, but then, "Why would anybody want to make them?"

Compare physical and chemical change?
Physical changes involve a change in appearance, such as size, shape, or state, without altering the chemical composition of the substance. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are reversible, while chemical changes are usually irreversible.
Compare the total amount of energy before and after physical and chemical changes?
In physical changes, the total amount of energy before and after remains the same as no new substances are formed. In chemical changes, there may be a difference in the total amount of energy before and after the reaction due to the formation of new substances and the breaking or forming of chemical bonds.
