1.	∆U is equal to A)isochoric workB)isobaric workC)adiabatic workD)isothermal workplease i want explanation also
Answer» qual to D)isothermal work.Explanation:Isothermal process is the process in which temperature of the SYSTEM remains constant. Therefore, INTERNAL energy remains constant. For an ideal gas in an isothermal process, ∆U=0=Q-W.where, ∆U= internal energy Q = HEAT ABSORBED or released W = work DONE by the system or on the system
