A substance must have the properties of physical properties in order to be observed and measured.
You can observe an object's color, shape, texture, size, weight, smell, taste, and temperature using your senses.
The five main senses used to observe things are sight, hearing, smell, taste, and touch. These senses help us gather information about our surroundings and form perceptions about the world.
No if you use your senses it is a physical change
You can use your five senses to observe both physical and chemical changes. For physical changes, you might notice changes in texture, color, or state (like ice melting into water) through sight and touch. In the case of chemical changes, senses like smell and sight can reveal new odors or color changes during a reaction (such as rust forming on iron). However, some chemical changes may not be easily detectable by the senses, especially if they occur at a microscopic level.
The use of the senses to gather information is known as sensory perception.
you cant
You can visually observe the color, opacity, viscosity of a substance. You can listen for audible sounds emanating from the substance. You can waft air currents over the substance to see if you can smell anything - NEVER directly sniff an unknown substance. You could touch the substance while wearing chemical resistant gloves to determine texture. The only sense you absolutely should not use is the sense of taste as you could be accidentally ingesting a poision or toxin.
