1.	Which one of the following equations does not correctly represents the first law of thermodynamics for the given process ?A. isothermal process`:q= - w`B. cyclic process `: q= - w`C. isochoric process `: DeltaE = q`D. adiabatic process `: DeltaE = -w`
Answer» Correct Answer - d According to1st law of thermodynamics, `DeltaE = q+w` Forisothermal process, `DeltaE = 0`. Hence, `q= - w` For cyclic process,`DeltaHE =0`. Hence, `q= -w` For isochoric process , `DeltaV =0`. Hence, `DeltaE =q` `( w= P DeltaV= 0)` For adiabatic process, `q=0`. Hence, `DeltaE= w`. For expansion into vacuum , `w=0` . Hence, `DeltaE=q`. Thus, only (d) is incorret.
