Examples: boiling, freezing, sublimation, evaporation, deposition etc.
During a physical change, the chemical composition of the matter remains the same, while its physical properties, such as shape, size, or state, may change. The individual particles that make up the matter do not change in a physical change.
Yes, a physical change occurs when matter changes state. This change is reversible and does not alter the chemical composition of the substance. Examples include melting, freezing, vaporization, and condensation.
When matter undergoes a physical change, its state may change (solid to liquid, liquid to gas, etc.), its shape or size may change, or its physical properties such as density or volume may be altered. However, the chemical composition of the substance remains the same before and after the physical change.
The expansion of matter upon heating is an example of a thermal expansion, which is the tendency of matter to change in volume, area, and length in response to a change in temperature.
A physical change in matter caused by a loss or gain of heat is called a thermal change.
phyiscal change
Of course. If you can change the solid to a gas you can turn the gas into a liquid then you can change the liquid into a solid. It is called changes of matter.
Color can be anywhere from a physcal change to a chemical change.
It's physical
Breaking glass is a physical change because there is NO chemical difference ... from before to after.
The wax melts
Physical. The metal wire is still a metal wire after the change.
It is a physical change caused by chemicals. Chemical changes are phyiscal changes.
Because physical state of water is changed from liquid to vapour.
A physical change
it is to do with dancing
Physical changes in matter, such as changes in shape or phase, alter its appearance without changing its chemical composition. This means that the substance remains the same at the molecular level even though it may look different. Examples include melting, freezing, and dissolving.
