physical properties
No. Chemical properties can only be observed during a chemical reaction, where the substance must be changed.
Yes, many physical properties can be observed just by looking at something, no need to change it.
can a chemical property be observed without changing the substance
No, a physical property DOES NOT change the identity of a substance. That would be a chemical property which DOES change the identity.
physical properties
Physical property is an aspect of matter that can be observed or measured without changing, Chemical property may only be observed by changing the chemicals identity of a substance. (this was copied off a scientific website) :)
A physical property can be observed without changing the material's composition. A chemical property can only be observed when a chemical change takes place.
physical properties are those that can be seen or measured without changing a material. chemical properties tell how the substance forms new substances when it mixes with something else.
chemical properties.
Physical :)
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
All physical properties.
yes
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.
chemical properties cannot be determined just by viewing or touching the substance and physical properties can be observed or measured without changing the composition of matter.
A physical property can be observed without changing the material's composition. A chemical property can only be observed when a chemical change takes place.
A physical property can be observed without changing what the substance is made of. A chemical property can only be observed by altering a substance through a chemical change.
Chemical Properties can be observed only when substances in a sample of matter are changing into different substances.
Chemical properties cannot be observed without changing its composition. ie: oxidation numbers Physical properties are properties such as melting point and boiling point. All that is needed to observe these are by placing the compound in a melting point apparatus etc.
Physical properties to a substance can be observed and documented without chemically changing them. Physical property examples are color, smell and size, for example.
