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
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.
Can a physical change be reversed?
yes they can because if you freeze water that doesn't prevent you from being able to change the water back into its original state
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 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 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.
Is molded clay physical or chemical change?
physical, because it can be easily reversed
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.
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.
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.
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.
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.
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 juice freezing and forming popsicles a physical or chemical change?
The process of juice freezing and forming popsicles is a physical change. This is because the change in state from liquid to solid is a physical change that can be easily reversed by allowing the popsicle to thaw back into liquid form.
What type of change is an eyeshadow physical or chemical?
it is chemical because it can not be reversed
What is physical change in matter?
