Physical change: Water freezing into ice Chemical change: Water being broken down into hydrogen and hydroxide ions after the addition of a pure metal.
atomic bomb., nuclear bomb, dynamite, volcanoes...
i dnt know i'm still searching on it....
Breaking, grinding, cracking are all examples of a physical change. The nature of the substance has not changed, just the size of the pieces has changed.
A physical change
Physical change of the paint, not the door.
No, it is a Physical Change. Physical Changes are concerned with energy and states of matter. A physical change does not produce a new substance. Changes in state or phase (condensation, melting, freezing, vaporization, sublimation) are physical changes. Other examples of physical changes include crushing a can, melting ice, and breaking a bottle. Chemical changes take place on the molecular level. A Chemical Change produces a new substance. Some examples of chemical changes include combustion (burning) and rusting of a metal.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
Phase change is a physical change.
It is a nuclear change because there is a change in the nuclear structure of Uranium.
Physical Change. =KDML= ;)
Physical change - make it frozen ; Chemical change - make it spoiled
The radioactive decay of radium is a nuclear change. This differentiates the transformation from a chemical or physical one.
In nuclear reactions the atom itself changes while molecules and/or structural organisation of atoms do in chemical and physical changes.
when fireworks go off, the energy released show a chemical reaction. gasses such as carbon dioxide and particles of smoke go up in the air.
melting any metal is physical. rusting iron is chemical
Physical changes can range from colour changes to change in tempricture.
No, it is a chemical change. ---------------------------------- Yes, it is a physical change because this change not involve a chemical reaction but a nuclear reaction followed by a change in the number of protons and neutrons.
Chemical Changes the substance and physical really dont change it as much examples of chemical: burning wood, physical: painting it Physical is basically changing color, looks,
non example of chemical change: one non example is ice. ice is NOT an example of chemical change.
