chemical properties can be observed only when the substances in a sample of matter are changing into different substances
they are harder to observe because youcan't be seen.
you can observe chemical reactions from its smell, colour, shape, or the change in it's properties
Yes, physical are on the outside and can be observed in a matter of seconds, whereas chemical properties have to be tested, which can take as long as years
Chemical changes are considered unseen because they occur at the atomic level, changing the actual structure of the thing. This is in comparison to a physical change, which is visible.
only when a change occurs and a new substance is formed
only when a change occurs and a new substance is formed
The way I remember the difference, is: a physical property is a property that you can observe without changing it (or observe without a chemical reaction). So properties like melting point, boiling point, density, color, hardness are all physical properties. A property like 'reacts with water' could only be observed by performing the reaction to observe the change.

Yes, all substances have inherent properties such as mass, volume, and density. These properties may not always be easily observable without specialized equipment or techniques.
Volume is a physical property.
.... by measurement with an device designed for one particular property: balance for mass, thermometer for temperature, ruler for length, spectrophotometer for color, photometer for light, etc.
