1.	The first law of thermodynamics for isothermal process isA. `q = - W`B. `DeltaU = W`C. `DeltaU = q_(v)`D. `DeltaU = - q_(v)`
Answer» Correct Answer - A According to first law of thermodynamics, `DeltaU = q+W` where, `DeltaU =` internal energy ` q =` Heat, w = Work done For isothermal process , `DeltaT = 0 , DeltaU = 0` `:. q = - W`
