The pressure -volume work for an ideal gas canbe calculated by using the expression w= -int_(V_(l))^(V_(f))p_(ex)dV.The workcan also be calculated from the pV - plotby using the area under the curve within the specified limit. When anideal gas is compressed(a)reversibly or (b) irreversibly from volumeV_(i) to V_(f), choose the correct option.

1.	The pressure -volume work for an ideal gas canbe calculated by using the expression w= -int_(V_(l))^(V_(f))p_(ex)dV.The workcan also be calculated from the pV - plotby using the area under the curve within the specified limit. When anideal gas is compressed(a)reversibly or (b) irreversibly from volumeV_(i) to V_(f), choose the correct option.
Answer» <P>W ( reversible)=w ( irreversible) w( reversible) `lt` w ( irreversible) w ( reversible) `gt` w ( irreversible) w(reversible)`=`w ( irreversible) `+p_(EX) DELTAV` SOLUTION :Look at Fig.page. Area under the curvein Figure. (a) Which is for irreversible compression is more than the area under tha curve in Figure.Which is for reversible compression. Hence, for compression `w( rev) lt w ( "irrev")`.
