A sample of an ideal gas is expanded `1 m^(3)` to `3 m^(3)` in a reversible process for which `P=KV^(2)` , with `K=6 "bar"//m^(6).` What is work done by the gas (in kJ) ?A. 5200 JB. 15600 kJC. 52 kJD. 5267 .6 kJ |
Answer» Correct Answer - A `intdw=-intP.dV` `implies w_("rev")=-int6.V^(2)dV` `=-6[(V_(2)^(3))/(3)-(V_(1)^(3))/(3)]"bar."m^(3),` `w=-5200 " kJ"` so, work done by the gas is 5200 kJ. |
