1.	In the question number 5, if the maiximum pressure is P then what is the pressur at the point 5? (in P-T diagram)
Answer» <P>`(2P)/(3)` `(4P)/(3)` `(3P)/(3)` None of these. Solution :Given: `P_(1)=P_(2)=2P_(3)=P` Since `1rarr2 and 3rarr4` are isobaric porcesses `THEREFORE` HEAT received = `nC_(P)(T_(F)-T_(i))` Accrording to question, `C_(P)(T_(2)-T_(0))=C_(P)(T_(0)-T_(3))` For process `2rarr3` i.e isochoric process `(P_(2))/(t_(2))=(P_(5))/(t_(5))=(P_(3))/(T_(3))` `therefore (P)/(T_(2))=(P_(5))/(T_(0))=(P//2)/(T_(3))`(From eqn(i)) or `T_(2)=2T_(3)` and `P_(5)=(P)/(2)(T_(0))/(t_(3))` soliving eqn (ii) using eqn (iii) we get `P_(5)=(3)/(4)P` `therefore` pressure at point 5 is `(3P)/(4)`
