Do chemical reactions always involve changes in energy?
no
How are physical changes and chemical changes related to your digestive system?
Physical changes are how the food is broken down. For now, it's still food. Chemical changes are when the food is broken down and absorbed. then, what's left is turned into feces. It's not food anymore.
Is firing pottery a chemical change?
Yes. Chemical changes occur during the calcination of ceramics for pottery.
What is the definition of chemical evidence?
Material produced by or used in a reaction involving changes in atoms or molecules. :D
Give an example of a reversible change?
An example of a reversible change is an ice cube meting into water and then changing back to an ice cube again if frozen. Another is chocolate melting when heated and changing back to a solid when cooled.
What chemical reactions are reversible?
All physical changes are reversible.
Is the reaction reversible?
chemical reactions are irreversible but physical changes are reversible
Are reversible changes and physical changes the same?
Reversible changes and physical changes are not exactly the same. Reversible changes can be undone and the original substance can be recovered, while physical changes alter the appearance or state of a substance without changing its chemical composition. Physical changes are usually reversible, but not all reversible changes are physical changes.
Are physical and chemical changes simply reversible and non reversible changes?
Chemical changes create new substances and cannot be reversed.Burning paperLighting a matchMixing sugar and waterPhysical changes do not create new substances and can be reversed.Crushing a canTearing paperChopping wood
Is making crisps from cooking oil and potatoes a reversible change or chemical reaction?
Most cooking processes are chemical reactions. Generally, the reactions are non reversible and once cooked, food cannot be returned to an uncooked state. So, frying potatoes causes a non reversible chemical reaction. The question is not as precise as it might be. Changes can be physical or chemical. They can also be reversible or non reversible but it is important to note that many chemical changes are reversible just as many physical changes are reversible.
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
Differences between physical changes and chemical changes?
Physical changes are changes that affect the form of a chemical substance, such as changes in state or shape, without changing its chemical composition. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are often irreversible.
What Is the difference between physical changes and chemical change?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
what is the difference between chemical change and physical changes?
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
Would freezing an object be physical change or chemical change?
Physical changes and Chemical changes are both the same - this would be a reversible change.
What chemical changes are reversible?
Chemical changes that involve physical changes, such as melting, boiling, or dissolving, are generally reversible. Reactions involving phase changes or reversible reactions where products can revert back to reactants under certain conditions are reversible. An example is the reaction between water and carbon dioxide to form carbonic acid, which can decompose back into water and carbon dioxide.
Can a chemical change be undone?
Some chemical changes are reversible, others are not.
