Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

In an Isothermal process the temperature is constant. Hence, the internal energy is constant, and the net change in internal energy is ZERO. Since the temperature outside the flasks was constant (room temp.) and since the expanded gas had not changed its temperature, no heat could had been transferred (Q=0). At the same time, since the volume of the flasks was constant, no work could have been done by the gas during the expansion (W=0). Therefore, ΔU=0.

then it shoulde be like ∆E = ∆H , but what is the effect of temperature on change in internal energy?
internal energy is a function of temperature
