What observations indicate that a physical change is occurring?

Answer 1

A physical change is something simple, or easy to reverse, like a change of state (Such as ice melting into water)

Answer 2

A physical change can be identified by sometimes something boiling ( water maybe) or even something being cut like wood off of a tree because the substance does not change molecules it just changes in other ways. Unlike a chemical change that completely changes and is a whole new substance. A physical change can even be ice melting because ice melting just turns the ice into water which has the same molecules as ice but ice is just in the soli state of water,(water also has a gas state which is water vapor).

Answer 3

If matter is measurably altered, but it retains its identity. For example:

You can cut a block of wood in two, but it is still wood.

If there is a change in a physical property which can be measured, temperature, pressure, volume, or density.

Answer 4

Some observations that indicate a physical change is occurring include a change in shape, size, color, or phase of matter (solid, liquid, gas). Physical changes do not alter the substance's chemical composition, so if you can reverse the change (such as melting and freezing water), it's likely a physical change.

Answer 5

A physical change is something simple, or easy to reverse, like a change of state (Such as ice melting into water)

Answer 6

Tearing a piece of paper or stretching a rubber band.

Answer 7

Maybe colors change, size changes, but ALWAYS changes back
