.... 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.
they are harder to observe because youcan't be seen.
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
smell , hear , see, taste , eat
Physical properties are things you observe with your eyes during chemical reaction e.g. Salt analysis the choking smell of ammonia u observed with your nose is a physical properties of ammonia
Tools such as rulers, thermometers, balances, graduated cylinders, and stopwatches can be used to observe and measure physical properties like length, temperature, mass, volume, and time. Additionally, spectrophotometers and pH meters can be used to measure properties such as light absorption and acidity.
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.

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.
Yes, you can use your senses to observe properties of a substance. For example, you can use sight to observe its color and texture, smell to detect any odors, touch to feel its texture and temperature, and taste to determine its flavor.
...Sounds like your taking basic chemistry:P Two physical properties are color and elasticity. So you understand physical properties are anything you can observe and do not change the objects chemical makeup.
3 physical properties of a banana are that it is yellow, its shape is usually curvy, and that it feels kind of smooth. Remember: physical properties are things that you can observe without changing the matter.
