(a)

Interpretation Introduction

Interpretation:

The density of Gallium in $\text{g}{\text{cm}}^{\text{-3}}$ 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,

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

(b)

Interpretation Introduction

Interpretation:

The melting point of Sodium chloride in Gallium scale has to be calculated.

Concept Introduction:

The melting point in Gallium scale is calculated from the formula below,

$\text{Melting}\text{point=}\frac{\text{Boiling}\text{point}\text{of}\text{Gallium(in}\text{Gallium}\text{scale)-Melting}\text{point}\text{of}\text{Gallium(in}\text{Gallium}\text{scale)}}{\text{Boiling}\text{point}\text{of}\text{Gallium(in}\text{Celsius)-Melting}\text{point}\text{of}\text{Gallium(in}\text{Celsius)}}$
