Starting at temperature 300 K, one mole of an ideal diatomic gas (γ = 1.4) is first compressed adiabatically from volume V1 to V2 = V116. It is then allowed to expand isobarically to volume 2V2. Assuming all processes are quasi-static, the final temperature of the gas (in K, to the nearest integer) is:
