(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.
(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.
(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.
(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:
Here,
P- Pressure
V-Volume
T- Temperature
n- Number of moles
R- Universal gas constant
(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.
