What happens to matter when it undergoes a physical and chemical change?
A chemical change cant be undone and a new substance, so in other words you cant reverse the effects and in the end you get ashes. An example of a chemical change would be burning paper and getting ashes. A physical change can be undone. An example of a physical change would be bending the paper because you can still get the paper back and no new substance is created.
When water changes to steam it undergoes a chemical change true or false?
False. When water changes to steam, it undergoes a physical change, not a chemical change. Heating water to its boiling point causes it to change from a liquid to a gas, but the chemical composition of water (H2O) remains the same.

It is usually very hard to change a chemical change BACK to its original substance. The answer to this is No
A physical change differs from a chemical change in that waste products are formed through chemical changes?
In a physical change, the substance retains its chemical composition, but its physical state may change, such as melting or freezing. In a chemical change, the substance undergoes a change in its chemical composition, resulting in the formation of new substances.
