1.	Based on first law of thermodynamics , which one of the following is correct ?
Answer» For an isochoric proces`,DeltaU =-q` For an ADIABATIC PROCESS, `DeltaU = -W` For an isothermal process`,q= +w` For a cyclic process,`q= -w` Solution :(a) `DeltaU = q+w`. For an isochoric process,`w = - P DeltaV =0`. Hence,`DeltaU = q_(v)` (b) For an adiabatic process , `q=0`. Hence, `DeltaU =w` (C ) For an isothermal process, `DeltaU =0` Hence, `q=-w` (d) For a cyclic process, `DeltaU =0`. Hence, `q= - w`
