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.

Does iron undergo change when it is moist?
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.
What is the properties of oil to the properties of the elements in oil?
the properties of oil are very different from the element in oil so this makes it easy to solvee
What is the differs between physical property and chemical property?
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.

What must happen for you to be able to observe an objects chemical properties?
only when a change occurs and a new substance is formed
Is it true Chemical properties aren't as easy to observe as physical 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
What are chemical properties harder to observe than physical properties?
they are harder to observe because youcan't be seen.
A substance always has properties even though they are difficult to observe?
chemical properties
What properties would you observe when you use a metric ruler?
You would observe the length of objects.
What are 5 positive properties of cardboard?
Physical properties are characteristics that can be recorded or measured using the senses. So, anything that you can observe or measure about a sheet of paper is fair game. Examples: paper is smooth, easy to crumple, lightweight, its color, its length and width, etc.
How can you observe chemical reaction?
you can observe chemical reactions from its smell, colour, shape, or the change in it's properties
Is it true that it is easy to observe vibrational motion?
no.It is not easy
When can chemical properties be observe?
chemical properties can be observed only when the substances in a sample of matter are changing into different substances
Which soil properties can you observe?
You can observe if the soil is clay, sand, or full of organic matter by the color. You can observe if the soil is compacted by how difficult it is to dig. You can observe if it has worms which is good because worms provide aeration and fertilizer. You can observe how wet the soil is.
Why are things grouped?
Dividing materials in groups makes it convenient to study their properties and also observe any patterns in their properties.
Difference between macroscopic and microscopic properties?
Macroscopic properties can be observed and measured on a larger scale, such as mass, volume, and pressure, while microscopic properties pertain to the individual particles that make up a substance, such as molecular structure and behavior. Macroscopic properties describe the overall behavior of a system, whereas microscopic properties provide insight into the interactions between particles at a molecular level.
What are the ways to observe physical properties in Science?
smell , hear , see, taste , eat
