a physical change is the form of matter but not in its chemical identity or is when the state or shape of matter is changed.physical change is reversable or temporary while a chemical is permenent or cannot be reversed.a chemical change is a change in which one or more kinds of matter are transformed into a new kind of matter.
(i) Physical change does not result in formation of new substances Chemical change result in formation of new substances (ii) Physical change is a temporary change Chemical change is a permanent change (iii) Physical change is reversible Chemical change cannot be reversed back (iv) e.g of Physical change-Dissolving of sugar in water to obtain a sugar solution e.g of Chemical change-Burning of sodium in chloride

physical change.the condition can be reversed by changing the temperature & it is only a temporary change.
science
It causes a physical change because it just lies on the hair, on it's cuticle.
Actually itz just a temporary physical change.........as u dont add on subtract anything frm the magnet exept heat.....,heat does not effect chemical properties of an iron magnet..
