1i have said dis b'fore...(donno how many of u actually saw it)...
when u have the pressure increased at constant temperature, the volume decreases rite..now as an external agent, work done by u on the system, shud be positive, so den why have many of the institutes given the answer to the second question as -414KJ??
plus when u actually increase the temperature at constant P, the volume as well increases, so by dis logic, the work done by u, an external egent "on" the system shud be negetive..but none of the options in the first Q. had any negetive option...what was this?
9no
aT/x is also valid enough
i think AIEEE board will give mark for both the ans
1Hey AIEEE MAths was easy but the approach had to be different than usual.The last year's paper was too easy substitutional level and people thought this year would also be the same and they dint get the same this year so how can u call it difficult. I mean everyone says Maths was difficult.It was rather good.
9i donno
this year jee maths and phy i felt there was 0 ambiguity
chemistry was ambiguos in jee while AIEEE chem was superb !!!
maths was stupid in AIEEE paper was set very poor standards
1But AIEEE is surely trying to catch up with JEE standards ,,.... whtat say??

i guess my risky guess payed off ( that was the only Q in maths i dint know so guessed in a desperate attempt to get full :) )
1Guys 1 st one is absolutely correct !!
tautology is not correct because the result is not always 1 !!
1not so gud joke....altough i understand that u have not checked all of ur answers.....bt even though not so gud.....
106p q ~q (p<-> ~q) ~(p<-> ~q) ( p<->q)
T F T T F F
T T F F T T
F T F T F F
F F T F T T
So u can see that
(i) ~(p<->~q) is equivalent to p<->q
(ii) ~(p<->~q) is NOT a tautology
