Answer: Option (B) is the correct answer.
Explanation:
A molecules that will have more number of hydrogen bonding will has highest boiling point because to break the hydrogen bonds high heat needs to be provided.
So, in the molecule 
there is presence of two alcoholic groups. Hence, it will have strongest hydrogen bonding as compared to the rest of molecules.
In the molecule 
there will be hydrogen bonding and dipole-dipole interactions. Hence, it boiling point will be slightly less than .
In the molecule 
, there will be only hydrogen bonding. Hence, its boiling point is less than .
In the molecule 
, there is no hydrogen bonding but there will be only dipole-dipole interactions. Hence, its boiling point will be the least.
Therefore, we can conclude that increasing order of boiling point will be as follows.

Answer:
Explanation:
Here, we want to get the new volume of the gas
What we need to know is the law that connects volume and pressure at constant temperature
The law that supports this is the Boyle's law
It states that the volume of a given mass of gas is inversely proportional to its pressure at constant temperature
Mathematically, we can have this as represented as:
We can proceed mathematically to solve as follows;
