Interpretation:

Whether the statement, physical appearance of a substance does not change because the composition does not change in physical separation is correct or not should be determined.

Concept introduction:

The mixture can be defined as a physically combined material made up of two or more different substances. The mixture can be of two types, heterogenous or homogenous. Heterogenous mixture is when the substances present in the mixture have different phases and the homogenous mixture is when the all the substances are present in the same phase.

Expert Solution & Answer

Answer to Problem 14SSC

The statement is not correct.

Explanation of Solution

In the physical change the chemical properties of the substances are remained, but the physical property is changed. The appearance of the substance is a physical property. So, in physical change, it is possible that composition is same, but the appearance of the substance is changed.

An example for this can be seen in freezing of water. The basic composition of water in liquid form and ice, which is solid form is same, but the ice is solid and water in unfreeze form is liquid.
