What else can I help you with?
Give one example of physical change that could be easily reversed?
Change of state from a liquid to a solid and back again.
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.
What are some characteristics for a physical change?
A physical change is a change that can be reversed easily and no new substances are made. Examples are state changes ie. solid to liquid or liquid to gas.
Is molded clay physical or chemical change?
physical, because it can be easily reversed
Burning of a cracker is a reversible or irreversible change?
Burning of a cracker is an irreversible change. Once the cracker is burnt, it undergoes a chemical reaction that cannot be easily reversed to its original form.

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 a lava lamp a reversible change?
No, a lava lamp is not a reversible change. The melting and mixing of the wax and oil inside the lamp is a physical change that cannot be easily reversed to its original state.
Is a light bulb a reversible change?
No, a light bulb is not a reversible change. When the filament inside the light bulb heats up and emits light, it undergoes a chemical change and cannot be easily reversed.
Is molded clay physical or chemical change?
physical, because it can be easily reversed
Burning of a cracker is a reversible or irreversible change?
Burning of a cracker is an irreversible change. Once the cracker is burnt, it undergoes a chemical reaction that cannot be easily reversed to its original form.
Why is a phase change only a physical change?
See "Related Questions". Phase changes are reversible by adding or subtracting heat. In many cases chemical changes are not easily reversed.
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?
How is sour milk a chemical change?
When milk turns sour, it is a chemical change because the bacteria in the milk ferment the lactose sugar into lactic acid, which changes the composition of the milk. This process cannot be easily reversed, making it a chemical change rather than a physical one.
Can thermal decomposition of water be reversed?
yes but not easily
