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.
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.
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.
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.
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.
Meeting butter for popcorn is physical or chemical?
physical because it can return to its solid state by cooling. chemical changes can not be reversed so easily
What is the difference between chemical and physical changes?
Chemical changes involve the rearrangement of atoms to form new substances with different chemical properties. Physical changes, on the other hand, only affect the physical state of a substance (such as its shape, size, or phase) without changing its chemical composition.
Can a chemical changes be reversed by physical changes?
Technically no..... however; the application of "extreme" physical forces can cause chemical change such as applying exiremely high pressure to coal to cause the formation of diamond.
What are the differences between the physical and chemical?
in changes. Physical changes can be reversed. E.g. if you were to melt a block of ice, and then freeze it again, it would to some degree be reversed. This is a physical change. However, if you were to burn a peace of toast, the change would be chemical. Once the toast is burnt you cant get it back.
If frost forms on a window is it a physical chang or a chemical?
Physical- that is water vapor freezing into ice. It can be reversed (warm up the window) Chemical changes don't reverse.
What are three differences between physical and chemical changes?
(i) Physical change does not result in formation of new substances Chemical change result in formation of new substances (ii) Physical change is a temporary change Chemical change is a permanent change (iii) Physical change is reversible Chemical change cannot be reversed back (iv) e.g of Physical change-Dissolving of sugar in water to obtain a sugar solution e.g of Chemical change-Burning of sodium in chloride
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.
