Interpretation Introduction

Interpretation: Volume of antifreeze Ethylene glycol added to car radiator having 6.50L at -20°C to be determined and boiling point of water-Ethylene glycol to be calculated.

Concept introduction

Boiling point is the temperature at which liquid turns into a gas.  Example: boiling point of water is 100°C .  That is water changes from liquid phase to gas phase.

ΔTb= Tb- Tb°

Where,

ΔTb Change in boiling point

Tb -  Boiling point of the solution

Tb° -  Boiling point of pure solvent

Boiling point elevation (ΔTb) is distinction between boiling point of the pure solvent (Tb°) and the boiling point of the solution (Tb) .

ΔTb= Kbm

Where,

ΔTb Change in boiling point

Kb Molal boiling point constant

m- Molality of the solution

Volume: A quantity of the substance which occupies three dimensional space within the container. The formula used to determine volume is,

Volume =massdensity
