The type of change that affects the state of matter but not the chemical makeup is called a physical change.

Here's why:

* Physical Change: A change in the form or appearance of a substance, but not its chemical composition. This means the molecules of the substance remain the same.

* Examples of Physical Changes:

* Change of state: Melting ice (solid to liquid), boiling water (liquid to gas), freezing water (liquid to solid), sublimating dry ice (solid to gas).

* Change in shape: Folding paper, cutting a piece of cloth, crushing a rock.

* Change in size: Stretching a rubber band, inflating a balloon.
