Whetherthe normal melting point of substance X would be less than or greater than or equal to 225°C to be explained. Concept introduction Freezing point: Freezing point is defined as the temperature at which liquid into solid. Boiling point: Boiling point is temperature at which the liquid into gas. Elevation of boiling point: Elevation of boiling point of a liquid is occurrence that boiling point of a liquid would be greater when another substance is added to it. Resulting, the boiling point becomes higher than the pure solvent. Depression of freezing point: Depression of freezing point is reducing in freezing point of a solvent when added non volatile solute. Volatile substance means easily vaporized at room temperature and non volatile means does not easily evaporate at room temperature.

Answer 1

Question

Chapter 10, Problem 109E

Interpretation Introduction

Interpretation: Whetherthe normal melting point of substance X would be less than or greater than or equal to 225°C to be explained.

Concept introduction

Freezing point: Freezing point is defined as the temperature at which liquid into solid.

Boiling point: Boiling point is temperature at which the liquid into gas.

Elevation of boiling point: Elevation of boiling point of a liquid is occurrence that boiling point of a liquid would be greater when another substance is added to it. Resulting, the boiling point becomes higher than the pure solvent.

Depression of freezing point: Depression of freezing point is reducing in freezing point of a solvent when added non volatile solute. Volatile substance means easily vaporized at room temperature and non volatile means does not easily evaporate at room temperature.
