Thermodynamics Part 5

One mole of an ideal diatomic gas expands from volume V to 2V isothermally at a temperature 27∘C and does W joule of work. If the gas undergoes same magnitude of expansion adiabatically from 27∘C doing the same amount of work W, then its final temperature will be (close to) ____ ‌∘C.
