Write 3 differences between chemical and physical change?
Okay now here goes in a physical change no chemical reaction takes place. in chemical change chemical reactions take place. A physical change is reversible but a chemical change is not.In a physical change no new substance is formed(A+B=B) in a chemical change new substances are formed(A+B=C)
Is producing something new a physical or a chemical change?
That depends on your definition of producing something new. If you cut lumber to build a table ... you have produced something new, but that is a physical change. Wood is still wood. But if you mean combining two or more substances, like hydrogen gas and oxygen gas, and, after burning, you form water, then that is a chemical change.
When sugar is heated for a short time a thick colorless liquid substance is formed What kind of change takes place?
The change that takes place when sugar is heated to form a thick, colorless liquid substance is a physical change. This is because the molecular structure of the sugar remains the same even though its physical state has changed from solid to liquid.

What is always a characteristic of a chemical change but not always a characteristic of a physical change?
When a chemical change takes place, the chemical structure of particles involved changes (i.e. one or more new substances are formed). In a physical change, the physical state of the particles involved changes (e.g. a solid melts and becomes a liquid). The chemical structure of the particles does not change, and no new substance is formed.
What is a substance when formed two or more substances are combined and a chemical change takes place?
a compound
Is the change that takes place when two or more substances interact to form new substances.?
A chemical reaction is the change that takes place when different substances react with one another to form new substances. The substances that react in a chemical reaction are called the reactants and the new substances formed are called the products.
When mixtures are formed a physical change takes place?
I am looking into it and let you know as soon as I decide.
Differences between chemical and physical properties?
In a physical change of matter, no new substances are formed. However, physical properties such as size, shape, color, or phase may change. Dissolving, melting, evaporating and grinding are examples of physical change.As a result of chemical change, one or more new substances with new and different properties are formed. The new substances are different from the original substance. Burning and the rusting of iron are examples of chemical change.
A substance formed when two or more other substances are combined and a chemical change takes place?
A compound is formed when two or more other substances are combined and a chemical change takes place. Pure water would be an example of a compound.

What changes of matter occur in respiration?
A change is said to be physical if no new substances are formed. Physical changes are temporary and can easily be reversed to give back the substances in their previous form. Freezing of water is an example of a physical change. A change is said to be chemical if new substances with different properties are formed. Chemical changes are permanent and cannot be reversed to give back the substances in their previous form. Burning of paper is an example of a chemical change.
