Yes.
You can observe physical, chemical, and characteristic properties of a substance and can be used to determine the usefulness of a substance by, giving us information about the substance usually using our 5 senses which are physical properties. Or being able to describe the substances ability to undergo changes to its composition to produce one or more new substances, chemical property. Or even just being able to identify whether or not the substance is pure or not can help us determine if the substance is hazardous or not. two other properties I did not mention were the qualitative and the quantitative properties.
Water is not a change of any sort. It is a substance. It can undergo physical and chemical changes.
hi guys ,this is the exact answer according to me,Physical changes occur when objects undergo a change that does not change their chemical nature. A physical change involves a change in physical properties. Physical properties can be observed without changing the type of matter. Examples of physical properties include: texture, shape, size, color, odor, volume, mass, weight, and density.
yes
No.
All substances have distinct physical and chemical properties, and may undergo physical or chemical changes. Physical properties, such as hardness and boiling point, and physical changes, such as melting or freezing, do not involve a change in the composition of matter.
These physical properties depends on the water temperature.
when a substance undergoes changes in its phase,its physical properties change.physical properties are properties you can observe without changing the material into another substances.
Chemical changes
Yes silicon can undergo physical and chemical changes.
Their buildings represent physical changes of the building materials.
no
All substances have physical changes.
None ------ Yes, can be melted.
Solid, liquid and gas.
