Atoms
Physical change. The paper is still a piece of paper; nothing happened to the chemical composition of it.
Physical change
the atoms dissolve with the atoms and the molecules to lock the sugar and salt / lock in to make the crystals
Chemical reactions also known as chemical change occurs when new products are produced due to the reorganization of atoms. The best example for this process is the change from raw food to cooked food.
Cause you're changing the direction of the atoms when you magnetize it.
As rubidium is a group one element, it has only the 5s1 electron in its outer energy level which makes it very reactive. So, if we were to drop some rubidium in water it would react rapidly to produce smoke and small sparks. There are lots of YouTube videos of this reaction so take a look.
Yes. Their atomic mass is different, among other things.
Physical Change: A change in which the atoms or molecules in a substance stay the same. Example: Ripping a piece of paper in half Chemical Change: A change that affects the type of molecules or atoms in a substance. Example: Burning wood The primary difference is that in a physical change, the composition of the substance remains the same, but in a chemical change, the composition of the substance changes.
Atoms
The transformation of a liquid to a gas.
There are millions of atoms in a cupcake pie. If you made a dot with a pencil on a piece of paper, there could be over a hundered atoms.
Physical change. The paper is still a piece of paper; nothing happened to the chemical composition of it.
An unmagnetized piece of iron has its atoms pointing in different directions, and opposing each other. When the iron is magnetized, the atoms are mostly pointing in the same direction, and the fields add together.
no it is not a physical change because folding a piece of paper does not chemicaly change it.
