Explanation:
It is known that more is the number of carbon atoms attached linearly to each other more will be the boiling point of the compound. This is because then more surface area is occupied by the compound with more intermolecular forces.
Hence, high heat is required to break the bonds therefore, boiling point rises. Also, more is the electronegative atom attached to the hydrocarbon more is the partial charges on the atoms of a molecule. Therefore, higher will be its boiling point.
Hydrogen bonding is more stronger in nature as compared to a molecule with dipole-dipole interactions.
Therefore, given compounds are ranked by their expected boiling point as follows.

Answer:
<h2>The answer is 70 kPa</h2>Explanation:
In order to find the pressure if the volume were increased to 375 ml we use Boyle's law
That's
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final pressure
From the question
P1 = 105 kPa = 105 , 000 Pa
V1 = 250 mL
V2 = 375 mL
So we have
We have the final answer as
<h3>70 kPa</h3>Hope this helps you
