We can observe the relise of force when a substance is canged into another substance.
Another diamond is the only substance hard enough to cut diamond.
Physical property is an aspect of matter that can be observed or measured without changing, Chemical property may only be observed by changing the chemicals identity of a substance. (this was copied off a scientific website) :)
The simplest substance in chemistry is the element, because elements cannot be broken down, only changed. Of the elements, the smallest and simplest is hydrogen.
A change that alters the form of a substance without changing it into another substance is called a physical change. This type of change does not involve a change in the chemical composition of the substance, only its physical appearance. Examples include changes in state (solid to liquid) or changes in shape (cutting or crushing).
No, diamonds are the hardest natural substance and can only be scratched or broken by another diamond.
This affirmation is generally true.
physical properties
No, a physical property DOES NOT change the identity of a substance. That would be a chemical property which DOES change the identity.
It is a mixture. A pure substance contains only one type of substance or one species of any substance or element. Sea water is a mixture of different salts dissolved in water. Thus, it is not a pure substance. Another point is that the different components of sea water can be observed separately.
True. Chemical properties are characteristics that can only be observed when a substance undergoes a chemical change, such as reactivity with other substances or the ability to undergo a chemical reaction.
Only in a nuclear reaction, otherwise no.
If the property can be observed without changing the chemical composition of the substance, then it is a physical property. If the property can be observed only through a chemical reaction, then it is a chemical property.
If the property can be observed without changing the chemical composition of the substance, then it is a physical property. If the property can be observed only through a chemical reaction, then it is a chemical property.
Physical properties can be observed without changing the chemical composition of a substance. Chemical properties can only be observed by changing the chemical composition of the substance. In a physical change, the chemical composition of the substance does not change. In a chemical change, the chemical composition of the substance changes.
A pysical property is like this: You take a stapler and bang it on the counter. It would be a broken stapler but it is still a stapler. It is still metal. Or even if you sawed it in half. It is still metal but it is metal in two pieces. A chemical property is like this: You take a block of wood and burn it. It is now ash. You have changed the material. Chemical changes are rarely reversable. You have taken wood and changed it into ash.
Another diamond is the only substance hard enough to cut diamond.
A physical property can be observed without changing what the substance is made of. A chemical property can only be observed by altering a substance through a chemical change.
