Is melting ice a chemical or physical change explain?
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.
What changes can't be reversed by physical means?
Changes that involve irreversible chemical reactions, such as burning wood to ashes or baking a cake, cannot be reversed by physical means. Once the chemical bonds are broken or rearranged, it is not possible to return the substances to their original state through physical processes alone.
Can a physical reaction be reversed?
Yes, physical reactions can often be reversed. This is because physical reactions involve changes in physical properties such as size, shape, or state of matter, which can typically be reversed by applying the appropriate conditions or processes to revert to the original state.
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
What change can be reversed easily?
A change that can be easily reversed is the alteration of one's hairstyle, such as cutting or coloring hair. If someone decides they don't like a new haircut or color, they can quickly grow it out or change it again with minimal long-term consequences. Similarly, changes in clothing choices can be easily reversed by simply selecting different outfits. These types of changes are typically low-stakes and can be adjusted with little effort.
Does chemical changes can be reversed by physical changes?
dont q
What do you call most changes that cannot be reversed?
irreversible
Explain Why physical changes can be reversed but chemical changes cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.

Could changes in any contributing factors have reversed the decline of the empire?
yes
Why physical changes can easily be reversed but why chemical cannot?
Physical changes are generally easy to reverse because NO ENERGY is produced by the substance.A Chemical change cannot be reversed because ENERGY is produced by the substance forming a new substance.
Chemical changes can be reserved by physical change?
No, chemical changes cannot be reversed by physical changes. Chemical changes involve the formation of new substances with different properties, while physical changes only affect the state or appearance of a substance without changing its chemical composition. Once a chemical change occurs, it cannot be undone by a physical change.

What is the difference between physically and chemical changes?
A chemical change is when something cannot be reversed and often a precipitate (solid) is formed. While a physical change can be reversed e.g bending a piece of wire.
When a volcano erupts what changes can be reversed?
Changes such as ashfall, lava flows, and pyroclastic flows can be reversed over time through natural processes, such as erosion and plant growth. However, the immediate effects of an eruption, such as loss of life, destruction of infrastructure, and environmental damage, may not be reversible.
