Chapter 3, Problem 14STP

Interpretation Introduction

Interpretation:

Whether the given data describes chemical or physical properties is to be determined.

Concept introduction:

Physical properties: The physical appearance and the properties are defined by the substance. They are constant for each substance.

Chemical properties:The reactive nature of the substance is defined by chemical properties. They have relative nature with other substances.

Answer to Problem 14STP

The given information is about physical properties.

Explanation of Solution

The given table is:

SELECTED PROPERTIES OF SUBSTANCES IN A MIXTURE
Item	Soluble in the water?	Soluble in alcohol?	Density ( ${\text{g/cm}}^{\text{3}}$ )	Particle size(mm)
sawdust	no	no	$0.21$	$1$
mothball	no	yes	$1.15$	$3$
Table salt	yes	no	$2.17$	$2$

The selected information explains the physical features of the substances. The individual substance shows different properties but like density is the physical property is fixed for the substance.

Conclusion

The given properties represent the physical appearance of the substance. The chemical properties depend on the reactive nature.
