How can you tell the difference between Physical change and chemical change?

Answer 1

A there are physical changes but, if you know the 4 chemical changes, anything else is a physical change.

1. Oxidation
2. Burning
3. Heat change
4. Bubbling (not boiling)

Answer 2

Physical changes alter the form of a substance without changing its chemical composition, such as melting or dissolving. Chemical changes result in the formation of new substances with different chemical properties, such as burning or rusting. Testing for new substances formed or irreversible changes can help distinguish between the two types of changes.

Answer 3

you can tell if it is a chemical change when a brand new substance can be formed. The properties in a chemical change are flammibility or reactivity. A physical change no new substance is formed and is usually reversible but not in all cases.

Answer 4

Signs of a chemical change include: color change (two clear liquids producing a yellow liquid), phase change (two liquids producing a solid precipitate or a gas), temperature change (two liquids combining and cooling the solution down or heating it up).

Answer 5

bubbling, change in color, blow up, smell, change in shape

Answer 6

physical is an original substance change by physical techiques. chemical is the same thing but chang by chemical techiques.

Answer 7

One way is perform a boiling point test or a melting point test.

Answer 8

you can tell the difference by a physical property is like an appearance and a chemical property is a change chemically like the density and if its soluble or not

Answer 9

A physical change does not change the chemical composition of the substance undergoing the change, however, a chemical change does cause a change in chemical composition.

Answer 10

A physical change doesn't involve a modification of the chemical formula of a compound.
