Question
How would I solve this?Suppose 6.32 moles of a monatomic ideal gas expandadiabatically, and its temperature decreases from 381 to 249 K.Determine (a) the work done (including thealgebraic sign) by the gas, and (b) the change inits internal energy. Thanks! How would I solve this?

Explanation / Answer
expanding adiabatically, we have 0=U +W => W=-U, which is the change in the internal energy W=-6.32*3/2*R(249-381)=+10.4 kJ (b) the change in the internalenergy U=-W= -10.4kJ
