An ideal gas is made to go through a cyclic thermodynamical process in four steps. The amount of heat involved are Q_(1) = 600 J, Q_(2) = - 400 J , Q_(3) = - 300 J " and " Q_(4) = 200 Jrespectively. The corresponding work involved are W_(1) = 300 J, W_(2) = - 200 J , W_(3) = - 150 J " and " W_(4) . The value of W_(4) is |

Answer» Solution :For cyclic process , `Q = DELTA U + W` or `600 - 400 - 300 + 200 = 300 - 200 - 150 + W_(4)` ` :. W_(4) = 150 J` |
