The color red results as a reflection from a particular wavelength of light off a compound in the skin of the apple. The compound in the skin is a chemical compound. The light ray is physical.
Cutting aluminum foil in half is a physical change. A physical change alters the form of a substance without changing its chemical composition. In this case, the aluminum foil remains aluminum foil after being cut in half, just in two smaller pieces. No new substances are formed during this process, so it is considered a physical change.
Cutting a glass tube is a physical change because the cut glass tube still has the same chemical composition as the uncut tube. Nothing has changed except the physical appearance of the glass tube.
Chemical. The hydrogen peroxide breaks down into water and elemental oxygen. Two new substances are created.
If you keep the cut apple under water if will stop the oxygen in the air to react with the apple and no browning will occur.
Physical Change is any change made to a substance without changing its chemical composition. For example, cutting iron or heating clay. when i cut iron i am still left with iron, when i heat clay, all i have is solid clay. i didn't change their chemical compositions
Cutting an apple is a physical change
It is a physical change because while the apple is cut into smaller pieces, it is still composed of the same materials. If you lit the apple on fire, that would result in a chemical change.
Physical change because you're just changing the shape of the apple, and not making the apple into a new substance
It is a physical change because the apple is still an apple and nothing changed the composition of what's in the apple.
Cutting anything is a physical change.
a physical change is a thing that changes an object but its still the object. such as cutting wood its still wood. but its unlike an apple because if you cut an apple it will eventually decay.
yes
It's a chemical change because the apple is oxidizing. It turns brown, because of the oxygen, hence the word " oxidizing".
The browning of an apple after being cut is an example of a chemical change called oxidation. When the apple's flesh is exposed to air, enzymes in the apple react with oxygen causing a chemical reaction that changes the color of the apple.
It is a chemical change because cut apples turn brown through the process of oxidation.
physical
No, it would be a chemical if someone cut open a apple and left it on a table for 20 minutes then coming back and the apple being brown.
