Changes in shape such as the tightening a clockwork spring or a change in phase such as freezing water to form ice are regarded as physical changes.
Changes where the different atoms of a substances are separated or combined with other atoms to form completely new substances are called chemical changes.
Chemical changes, such as burning carbon in oxygen to form carbon dioxide are usually accompanied by physical changes such as increasing temperature.
a change in size, shape or the state of matter is a physical change. True for A+.
This is a physical change. An example is breaking glass. It does not change its material, but its size shape or state. A chemical change is where it reacts with something. Iron rusting is an example, as the iron reacts to water.
i mean change
The change in which no new kinds of matter are formed but the size, shape or state of the matter may change is known as a physical change.
When a physical change takes place, a certain element or chemical will change its shape and in many cases, the volume too. Water takes the shape of the mold casing once it freezes.
a change in size, shape or the state of matter is a physical change. True for A+.

IT IS PHYSICAL change
physical change is change in the physical properties of matter that does not involve a change in its composition
A physical change is a change in the form of matter but not the chemical composition of it.

A physical change is simply, a temporary change, which changes the physical characters of an object like its color, shape, size etc. It is a reversible change.
This is a physical change. An example is breaking glass. It does not change its material, but its size shape or state. A chemical change is where it reacts with something. Iron rusting is an example, as the iron reacts to water.
"A physical change occurs when some of the properties of a material change, but the substances in the material remain the same." "...any actions that change the size and shape of a material, but not its composition." if the shape/form is changed but not its makeup, then that change is physical
i mean change
A physical change is the change of size, form, or shape of a material,but not in its chemical composition. There are 5 types of physical change: Evaporation, Condensation, Melting, Freezing, and Sublimation.
