Chapter 5, Problem 5.73P

Interpretation Introduction

(a)

Interpretation:

To justify whether the given statement is true or false.

Concept Introduction:

According to phase diagram, the three phases of any substance is inter convertible in between. The solid can be converted into liquid by heating it up to its melting point and the process is known as melting or fusion.

Interpretation Introduction

(b)

Interpretation:

To justify whether the given statement is true or false.

Concept Introduction:

According to phase diagram, the three phases of any substance is interconvertible in between. The liquid can be converted into gaseous form by heating it up to its boiling point and the process is known as boiling.

Interpretation Introduction

(c)

Interpretation:

To justify whether the given statement is true or false.

Concept Introduction:

According to phase diagram, the three phases of any substance is interconvertible in between. The solid can be converted into liquid by heating it up and liquid is further into in to gaseous form by adding continues heat until it reaches to its boiling point.

Interpretation Introduction

(d)

Interpretation:

To justify whether the given statement is true or false.

Concept Introduction:

According to heating curve, heat of fusion is a heat applied to a 1.0 g of solid substance to convert it in to its liquid phase.

Interpretation Introduction

(e)

Interpretation:

To justify whether the given statement is true or false.

Concept Introduction:

Heating curve describes that the amount of heat required to vaporize 1.0 g of liquid at its normal boiling point is called as Heat of vaporization.

Interpretation Introduction

(f)

Interpretation:

To justify whether the given statement is true or false.

Concept Introduction:

The heat of vaporization is the amount of heat that is required to evaporate 1.0 g of liquid to gas form at its normal boiling point.

Interpretation Introduction

(g)

Interpretation:

To justify whether the given statement is true or false.

Concept Introduction:

Heat of vaporization is the amount of heat required to evaporate 1.0 g of liquid to gas at its normal boiling point. The amount of heat is required to convert 1.0 g of solid to its liquid form is called as Heat of fusion.

Interpretation Introduction

(h)

Interpretation:

To justify whether the given statement is true or false.

Concept Introduction:

Melting is a process in which the solid is heated to its melting point and gets converted into liquid. Crystallization is a process in which liquid is cooled to temperature to form a solid form of it.

Interpretation Introduction

(i)

Interpretation:

To justify whether the given statement is true or false.

Concept Introduction:

Exothermic process is a process during which system releases energy whereas endothermic process is a process during which system absorbs energy.

Interpretation Introduction

(j)

Interpretation:

To justify whether the given statement is true or false.

Concept Introduction:

Melting is a process in which the solid is heated to its melting point and gets converted into liquid. This liquid formed from solid have the same molecules in it. For getting solid once again, liquid is required to be cooled back.

Interpretation Introduction

(k)

Interpretation:

To justify whether the given statement is true or false.

Concept Introduction:

Sublimation is a process in which a direct formation of gas form from solid form of substance occurs.
