The most important thing for your to remember is that in a physical change the composition of a substance does not change and in a chemical change the composition of a substance does change.
It is a physical change because when you have a chemical change it changes the properties and makes it into a new thing, and it can't be reversed. Physical changes are usually just changes of states (solid, liquid, gas) and a physical change can be reversed.
no it is a physical change the tree did not change into a different thing it simply changed in size

Tearing a piece of tin foil is a physical change because the substance's chemical composition remains the same before and after tearing. The appearance and physical structure of the tin foil may change, but no new substances are formed during the tearing process.
Physical change. The paper is still a piece of paper; nothing happened to the chemical composition of it.
you need to know what it is
The most important thing to remember is that when you let go of the throttle the steering stops working.
Since a physical change is something that happens to you, then you and any living thing is involved in a physical change. For example, if you are growing, you are involved in that physical change, because it is happening to you. Hope this helped!!

Depends on your age currently. The important thing to remember is that you can never change another person, the only thing you can change is how you react to that person. Its all about setting healthy boundaries.
the most important thing to remember about steering pwc is to keep the craft moving through the water
a physical change , something that is one thing but change into another
The most important thing to remember is that when you let go of the throttle the steering stops working. This is because the when you turn the handle bars it directs the flow of water out the back. If there is no water flowing there is no steering power.
The important thing to remember about the relationship between mass and weight is that mass is the amount of matter in an object, while weight is the force of gravity acting on that object. Mass remains constant regardless of location, while weight can change depending on the strength of gravity.
melting is a physical change. freezing is also a physical change. the only thing that changed was the state of matter. a chemical change for example is buring, the substance changes to co2 and h2o.
Just remember- The opposite sides are ALWAYS equal.
