An ideal gas expands from the volume of 1xx10^(-3)m^(3) to 1xx10^(-2)

1.	An ideal gas expands from the volume of 1xx10^(-3)m^(3) to 1xx10^(-2) m^(3) at 300K against a consta pressure at 1xx10^(5) Nm^(-2). The work done is ............
Answer» `-900 J` 900 KJ 270 KJ `-900 J` Solution :`w=-PDeltaV` `w=-(1xx105 Nm^(-2))(1XX10^(-2)m^(3)-1xx10^(-3)m^(3))` `w=-10^(5)(10^(-2)-10^(-3)) Nm` `w=-10^(5)(10-1)10^(-3)J` `w=-10^(5)(9xx10^(-3))J` `w=-10^(5)(9xx10^(-3))J` `w=-9xx10^(2)J` w=-900 J
