Most of the physical changes are ___ change
Answers
As we know that all physical changes are reversible and their mass does not change.
Some examples are changes of shape, changes of states, and passing electricity through a copper wire.
Physical changes could be:
Melting, freezing, boiling/evaporating, condensing, deposition and sublimation.
Many physical changes also involve the rearrangement of atoms most noticeably in the formation of crystals.
Most of the physical changes are reversible, but reversibility is not a certain criterion for classification. Although chemical changes may be recognized by an indication such as odor, color change, or production of a gas, every one of these indicators can result from physical change.
As we know that,
Physical changes are those particular changes which when occurring on a body results to the change in their shape, size.
Or in a simple way, we can say that, those changes which are not chemically occurs are called as physical changes.
While the reversible changes are those changes that can be reversed. like, if we press a ball it becomes falt, but the ball can be redrawn in its initial shape and size by undone the process.
So, such changes are termed as physical as well as reversible changes.
We know that all the physical changes are reversible.
Hence, we can say that,
Most of the physical changes are reversible change
