Question

how can an you explain physical change with experiment?

Answer 1

the change that takes place physically in any substance i.e., the changes that don't bring any sort of chemical changes or change in composition of the substance are known as physical changes.
these are reversible changes.
for example:- the melting of wax when a candle is burnt. the wax can be reversed to form the same candle again. hence it is a physical change.

Answer 2

HEY MATE HERE IS YOUR ANSWER

PHYSICAL CHANGES :

The changes that is temporary that is reversible

EXPERIMENT:

AIM: To prove physical changes

MATERIALS
REQUIRED: Water ,Ice tray,fridge (refrigerator)

PROCEDURE :
(i) We can observe that water is in liquid state
(ii)Then pore the water in the tray
(iii)Keep it in the refrigerator
(iv)After half an hour take it out

OBSERVATIONS :
-we can observe that the water which was I liquid state has changed into solid ice cubes
