Why can a physical change be easily reversed?
it can be easily reversed because nothing new is produced. it is the same particles but just rearranged. it is just a change in size, shape or state ***IT IS REVERSIBLE*** but what physical change is not easy to reverse?
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.
What is physical change in matter?
A physical change is a change to a substance/object which can be easily reversed, and no new substance is formed from it (as opposed to chemical change). The state of matter is usually changed, for example, turning from a solid to a liquid. e.g. ice cube melting
Why is Breaking of glass a physical change?
A physical change can be reversed, for it does not change what the object is made of. The glass, even when broken, is still glass. It can be put back into its original state (possibly through melting) because it never changed what it was made out of.
Is making salt by mixing sodium and chlorine together a physical or chemical change?
It is a physical change because the reaction can easily be reversed and no heat is involved.
What are example of a physical change that can be reversed and an example of a physical change that cannot be reversed?
An example of a physical change that can be reversed is melting ice into water; this can be reversed by freezing the water back into ice. An example of a physical change that cannot be reversed is breaking a glass; once the glass is shattered, it cannot be returned to its original form.
Evaporation a physical change?
Yes, because it can be reversed by condensation. Physical change = Reversible Chemical change = Irreversible
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.
Is molded clay physical or chemical change?
physical, because it can be easily reversed
Is a given change a chemical or a physical change?
It depends. Physical can be easily reversed. Chemical is hard, if not impossible to reverse.
Give one example of physical change that could be easily reversed?
Change of state from a liquid to a solid and back again.
Can a physical change always be reversed?
Yes, physical changes can usually be reversed because the substance's molecular structure remains the same. For example, melting ice into water and then refreezing it back into ice is a reversible physical change.
When an egg is cooked is this a physical change?
Cooking an egg is a chemical change because it cannot be reversed.
Is anamolous expansion of water a chemical or a physical change?
physical change.the condition can be reversed by changing the temperature & it is only a temporary change.
Why physical change can easily be reversed but chemical change 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.
Is transferring graphite from pencil to paper when writing a chemical or physical change?
physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
Is A log burned leaving ash a physical change?
No, it's a chemical change. A physical change is one which can be reversed. Like ice to water to ice etc.
