In the given \[(V-T)\] diagram, what is the relation between pressure \[{{P}_{1}}\] and \[{{P}_{2}}\]?

A) \[{{P}_{2}}>{{P}_{1}}\] 

B)                  \[{{P}_{2}}<{{P}_{1}}\]              

C)                 Cannot be predicted            

D) \[{{P}_{2}}={{P}_{1}}\]                    

Correct Answer: B

Solution :

\[{{P}_{1}}>{{P}_{2}}\] As V = constant \[\Rightarrow \,P\propto T\] Hence from \[V-T\] graph \[{{P}_{1}}>{{P}_{2}}\]
