Interpretation:The property that helps in distinguishing the sodium chloride from the other solids in the mentioned table should be determined.
Concept Introduction: A change that affects the form of a substance but not its chemical composition is said to be physical.

Answer to Problem 5LC
The property that helps in distinguishing sodium chloride from the other solids in the mentioned table is melting and boiling points.
Explanation of Solution
The temperature at which a given solid material changes from solidstate to liquid is said to be its melting point whereas the temperature at which a given liquid material changes from a liquid state to vapor is said to be its boiling point.
In the mentioned table, the state is the same for all that is solid and the color for sulfur and gold is yellow. So, these physical properties cannot be considered to distinguish sodium chloride from the other solids. The melting and boiling points are unique for each solid thus, the property that helps in distinguishing sodium chloride from the other solids in the mentioned table isthe melting and boiling points.
Melting and boiling points are the properties that help in distinguishing sodium chloride from the other solids in the mentioned table.
