if A directly varies as B B directly varies as CThen A must directly varies as C ....now we know Pressure inversely varies as Temperature then ,PV=nRT (ideal gas equation)here P directly varies as Tcan u please help me out???

i think there is some mistake in your  concept. in ideal gas equation  V is the volume of the container,if  V is constant, then P is dirertly proportional to T.  also , P is due to the randomness  of molecules  and randomness is due to kinetic energy of molecules , now if we  increase  T ,K.E. will increase  which  will increase P and vice vesra on keeping the V constant.

IF THIS INFORMATION REALLY HELPS YOU THAN PLZ  APPROVED THIS ANS.

THANK YOU.
