Which one is not an example of a chemical change Leaves on trees changing color A cake baking Food being digested All are examples of chemical changes?
All are examples of chemical changes
Is cutting of tree a chemical change?
No. Trees' leaves change colors beacuase when winter comes around, they will not have the energy to keep leaves, so they seal off the leaves from the rest of the tree. When the leaves are cut off from the rest of the tree, the chlorophyll in them dies, and turns brown.
Is cutting trees is physical or chemical change?
chemical change..... we just talked about this in science today and that is what my teacher said
Is the cutting of trees a physical or chemical change?
The act of cutting the tree is a physical change. However, there are chemical changes that take place as a result of cutting the tree. All plants have an ability to "feel" when they are being damaged and the plant cells around the damaged ones stiffen to attempt to prevent further damage.
Is egg cooking is a physical or chemical change?
This is a chemical change. Remember: An easy way to determine whether or not a change is chemical or physical is to ask if the process is reversible. Take the evaporation of water into account. When water evaporates, it can condense back into liquid water. It can be reversed because it is a physical change. Chemical changes are often permanent. Take the burning of wood, for example. This is a chemical change. Once you light wood on fire, it turns into gas. Only the trees and plants around you can take this gas and through photosynthesis, turn it back into wood. So it is a non-reversible process, and is a chemical process.
Examples of chemical changes in the nature?
Examples of chemical changes in nature include wood burning in a forest fire, photosynthesis, the formation of sulfuric acid in volcanic vents, and the fixing of nitrogen in lightning bolts and bacteria.
How does chemical change occur during a tornado?
A tornado is a physical process, not chemical. Tornadoes, though can sometimes start fires by breaking gas lines.
Is tearing leaves off of trees a physical or chemical change?
PHYSICAL
When fall arives and the leaves on the trees change colors is it chemical?
These are chemical changes.

Why is a tornado a physical change?
A tornado moves air and objects from one place to another and can tear apart buildings and trees. However, in all of this the chemical composition of everything hit by the tornado remains the same. Therefore all changes in this case are physical.
Is growing a flower a chemical or physical change?
A tree growing is a chemical change because the chemical reaction that happens in the trees cells causes the carbon dioxide and water to become sugar (food) for the plant to grow and oxygen it can "exhale" much like we exhale carbon dioxide.
What are the agents of biological weathering?
The agents of "weathering" is both the agents of the physical and the chemical weathering combined. Agents of physical weathering can be: wind, water, sun, ice, gravity, rain, etc. Agents of chemical weathering may be: acid from roots, acid rain, oxidation/reduction (rusting), carbon dioxide, etc. They are the same because both physical and chemical weathering lead to erosion of rocks. In other words, both help rocks break down into smaller pieces. They are also the same because both physical and chemical weathering can occur with the same agent. For example, TREES. The roots of trees release acid to break down rocks (chemical weathering) while the roots of trees also grow into the cracks of rocks and help break them apart (physical weathering). Note that weathering is just the beginning process of erosion. Erosion is when stuff actually breaks down into smaller pieces.
