Chapter 9, Problem 71QAP

Interpretation Introduction

(a)

Interpretation:

Whether the given statement is true or false needs to be determined.

In the phase diagram for a pure substance, triple point is temperature and pressure value at which the substance can boil, freeze and sublime simultaneously

Concept introduction:

Triple point is that point on the phase diagram at which all the three phases, liquid, solid and vapor, are in equilibrium with each other.

Interpretation Introduction

(b)

Interpretation:

Whether the given statement is true or false needs to be determined.

The boiling point of CHF₃ is more than CHCl₃ due to hydrogen bonding in CHCl₃.

Concept introduction:

Hydrogen bond is a strong type of dipole force which act between hydrogen atoms bonded to comparatively highly electronegative atoms specially fluorine, oxygen or nitrogen atom in a molecule and an unshared pair on such atoms of the neighboring molecule. There are two types of hydrogen bonding; intermolecular and intramolecular hydrogen bonding.

Interpretation Introduction

(c)

Interpretation:

Whether the given statement is true or false needs to be determined.

The melting and boiling point of a compound is independent of the strength of covalent bonds in it.

Concept introduction:

Covalent bonds are intermolecular bonds which are formed by sharing of electrons between two or more atoms. These can be formed by sharing of electron/s between same or different type of atoms.

Interpretation Introduction

(d)

Interpretation:

Whether the given statement is true or false needs to be determined.

The pressure deceases due to decreases in the amount of a condensable gas is reduced in a tank.

Concept introduction:

Ideal gas law is the relationship between the pressure, volume and temperature of a given amount of gas. Its mathematical expression is as follows:

PV= nRT

Here,

P- Pressure

V-Volume

T- Temperature

n- Number of moles

R- Universal gas constant

Interpretation Introduction

(e)

Interpretation:

Whether the given statement is true or false needs to be determined.

The temperature above which there is only gas phase is known as the critical temperature.

Concept introduction:

The critical temperature is the temperature below which any phase of a substance can be present but above it, there is no solid and liquid phase exist. Thus, only vapor phase of the substance is present at that point.
