1.	An ideal gas is expandendisothermallyfrom(P_(1) V_(1)) andto (P_(2)V_(2)) against a constantexternalpressure. Whichof the following is/arecorrect regardingabove process ?
Answer» <P>If `P_(ext)=P_(2)`piston will not stop automatically ATTHE final state If `P_(ext)=P_(2) `piston will not stop automatically atthe final state Magnitude of workduring expansioncan vary in the rangeof `0le\|W\|leP_(2)(V_(2)-V_(1))` Work will be zero when `P_(ext)` iszero and will bremaximumwhen `P_(ext)`is eqaulto pressure of system at final state Answer :B,c,d
