Chapter 1, Problem 25GQ

(a)

Interpretation Introduction

Interpretation:

The given observation should be reported either as qualitative or quantitative.

Concept introduction:

Qualitative: The quality of something rather than its quantity.  A property that can be observed but not measured numerically.

Quantitative: A property that can be measured numerically and to determine the amount or proportions of its chemical constituents.

(b)

Interpretation Introduction

Interpretation:

The given observation should be reported either as intensive property or extensive property.

Concept introduction:

Intensive property: A physical property of a system that does not depend on the system size or amount of material in the system. Intensive properties can be used to identify the substance.

Extensive property: A physical property of a system that does depend on the system size or amount of material in the system.

(c)

Interpretation Introduction

Interpretation:

The volume has to be calculated.

Concept introduction:

Density:

Density can be defined as property that links mass of an object to its volume.  It derived quantity and its unit is $\text{g}{\text{ml}}^{\text{-1}}$ for liquids and $\text{g}{\text{cm}}^{\text{-3}}$ for solid.  The density of material can be calculated with the help of formula,

  $\text{Density=}\frac{\text{Mass}\left(\text{g}\right)}{\text{Volume}\left(\text{ml}\text{or}{\text{cm}}^{\text{3}}\right)}$
