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.
no new substances are formed during physical change
A physical change may be accompanied by
1. change of state
2. change of phase
3. change of color, etc. but no change in chemical composition takes place
No physical change does not produce new products. Chemical change does. In a physical change there is only a change in the state of the product, it will still remain the same
No, a physical change produces the same substance in a new state. For example, ice melting to liquid water is an example of a physical change; in both states, the substance is water.
No. It remains the same substance, though it may possess different properties.
no
Yes
This is a chemical change.
If you burn something it is a chemical change, however if you melt of boil it, it is a physical change.

lighting is a chemical change
Distilling is a physical change.
chemical
That would be a chemical change.
Producing heat is caused by a chemical process which results in physical changes. The cause is chemical. The effect is physical. :) :D

When something fizzes and foams, it's producing some sort of gas within it, thus it's going from a solid/liquid to a gas (a physical change). But, this gas is likely not the same material that it came from. it's just a byproduct of a chemical reaction with in it (a chemical change).

A physical change is one where just the appearance of something changes and a chemical change is where the genetic makeup of something changes.
Smoke is not a change but a complex mixture; producing smoke is a chemical process.
