1.	Which one of the following equations does not correctly respresents the first law of thermodynamics for the given process?A. Isothermal process: `q= -w`B. Cyclic process: q= -wC. Adiabatic process: `Delta E=q`D. Expansion of a gas into vaccum: `Delta E=q`
Answer» Correct Answer - C Accoring to 1 st law of thermodynamics, `Delta E=q+w`. For isothermal process, `Delta E=0`. Hence, `q= -w` For cyclic process, `Delta E=0` Hence, For expansion into vaccum, `w=0`. Hence `Delta E=q`.
