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 :

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