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.
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
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.
What name do you give to temporary changes into materials?
Temporary changes in materials are often referred to as physical changes. These changes do not alter the chemical composition of the material and can usually be reversed by physical means. Examples include changes in state (e.g. melting, freezing) or changes in shape.
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

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.
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.
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.
