Question

There are two samples $A$ and $B$. $A$ is Methanol and $B$ is Ethanol. Both are heated both at the same rate in closed container separately. Which one is correct about the above test?

• A. At ${60}^0$C, container $A$ and $B$ both have liquids in them
• B. At ${80}^0$C, container $A$ and $B$ both have vapours in them
• C. At ${70}^0$C, container $B$ has liquid and $A$ has vapours
• D. All the above

Answer 1

The correct option is D All the above

Methanol has a boiling point of ${64.7}^0$C whereas ethanol has a boiling point of ${78.24}^0$C. So, all the statements are correct.
