Physical changes occur when objects or substances undergo a change that does not change their chemical composition. This contrasts with the concept of chemical change in which the composition of a substance changes or one or more substances combine or break up to form new substances. In general a physical change is reversible using physical means.
Physical changes . Why we call them physical changes? A reversible change might change how a substance looks or feels (Changing the physical appearance), and it is easy to turn it back again. But it doesnât produce new substances. E.g. â Water can change into ice. Ice can change into water. Here only the state of the substance (liquid water) changes, but not the substance (water). Examples of reversible changes . Melting. Example (1) â When chocolate is warmed until it melts, the melted chocolate can be changed back into solid chocolate by cooling. Example (2) -When candle wax is heated, the solid wax melts and becomes a liquid.
