In a "physical change" a new substance is not created. In a "chemical change" a new substance is created. This applies to changes in states of matter.
For example, ice, water, and steam are all the same substance, even though they exist in three different states. The elements of which they are comprised do not change.
Sometimes you may be able to precipitate elements out of a substance through a phase change. In a mixture of alcohol and water you can fairly quickly boil out the alcohol.

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.
Why is the boiling point of water a physical change?
It's not a chemical change because the only the temperature and phase changes. The properties may be altered somewhat, but it the same chemical compound. No atomic bonds are broken or formed, there are no new substances formed, and none of the signs that indicate a chemical change are present. Some of the water is changing from a liquid to a gaseous state, and can be returned to a liquid state, unchanged, by cooling it.
Do the properties of a substance change if the substance changes from a liquid to a gas?
Well, one of a substance's properties is whether it's a liquid or a gas or a solid. This is a physical property. If you mean chemical property, then no, it doesn't change with a change of phase.
Does a physical change mean that something has matured or grown up?
A physical change doesn't involve the molecule composition of a substance.
a change in the chemical properties of substance results in a?
A substance can take on three physical states: Solid, liquid, or gas. The main physical changes from a thermodynamic standpoint are the amount of entropy(disorder) of the molecules of the substance. Density, temperature, volume are also characteristically different at each physical state and can be used to manipulate compounds between the three.
What does matter can change state mean?
The same substance can exist either as a solid, liquid or a gas and can change state depending on the temperature or external pressure.
What does the word fiber mean?
Fiber can mean two things. Fiber is a thread formed from a vegetable tissue, mineral substance, or textile. Fiber can also mean a substance formed of such threads.

What does a substance mean?
A pure substance is a substance that cannot be separated by means of physical separation but only by chemical. It is a change in time.

Does a physical change mean you form a new substance?
no, that's would be a chemical change :) .
What does product mean science?
a substance that results from a chemical change
Is plastic physical or chemical?
If you mean that something is demonstrating plasticity, that would be a physical change.If you mean that plastic (a substance) is being formed, that's a chemical change.However, "plastic" itself is not really a change of any kind, so the best answer is "No."

What does the name Vapour mean?
a visible suspension in the air of particles of some substance. in other words, a substance in the gaseous state (a gas state) and then distinguished from the liquid or solid state.

Well, one of a substance's properties is whether it's a liquid or a gas or a solid. This is a physical property. If you mean chemical property, then no, it doesn't change with a change of phase.
