Chemical Change - Someone toasting bread until it is crisp. (Or just cooking in general, but does not apply to all types of food)
Physical Change - Someone pouring one of those Crystal Lights into water.

What are 2 physical properties?
...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.
Is water freezing at 0 degrees a chemical property?
no thats physical bc it doesnt result in a new substance, its just a different state of matter. look in ur book lazy!!
Which type of chemical and physical changes you observe in daily life?
Well a Chemical change means that what ever changes can't change back. For example if u have normal paper then burn it that's a chemical change and that's why a chemical change is so important.
Is it usually possible to observe physical objects breaking physical laws?
false
A substance always has properties even though they are difficult to observe?
chemical properties
Chemical or physical something you can observe?
Physical changes are those that can be observed.
Is yellow solid physical or chemical property?
physical (because you can observe it without inducing a chemical reaction).
What are chemical properties harder to observe than physical properties?
they are harder to observe because youcan't be seen.
Is volume a physical property or chemical?
Volume is a physical property.
What properties are not as easy to observe?
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.
What chemical and physical weathering do you observe in your home and campus Describewhat happens to the object?
itjj
Must a new substance be formed when you observe a chemical property?
Yes , it should or else it is a physical property
What is the difference between chemical property and physical 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.

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
. To categorize the elements what reactions did Mendeleev observe?
These are of course chemical reactions, for example oxydation.
