The pressure volume work for an ideal gas can be calculated by using the expression W=-int_(V_(i))^(V_(f))p_(ext)dV. The work can also be calculated from the pV-plot by using the area under the curve within the specified limits. When an ideal gas is compressed (a) reversibly or (b) irreversibly from volume V_(i) to V_(f). choose the correct option.

1.	The pressure volume work for an ideal gas can be calculated by using the expression W=-int_(V_(i))^(V_(f))p_(ext)dV. The work can also be calculated from the pV-plot by using the area under the curve within the specified limits. When an ideal gas is compressed (a) reversibly or (b) irreversibly from volume V_(i) to V_(f). choose the correct option.
Answer» `W_(("reversible")) = W_(("IRREVERSIBLE"))` `W_(("reversible")) lt W_(("irreversible"))` `W_(("reversible")) gt W_(("Irreversible"))` `W_(("reversible"))=W_(("irreversible"))+p_(ext)*DELTAV` Solution :`W_(("reversible")) lt W_(("irreversible"))` Area under the curve is ALWAYS more in irreversible compression as can be seen from FIGURE. (a) and (b)
