    Adiabatic Process of uranium fission bomb

    okay i did TV\exp{γ-1} = constant T = \frac{constant}{V\exp{γ-1}} dT = (1-γ)V\exp{-γ)dV

    Adiabatic Process of uranium fission bomb

    Homework Statement The fireball of a uranium fission bomb consists of a sphere of radius = 15m and temperature 300,000K shortly after detonation. Assuming that the expansion is adiabatic and that the fireball remains spherical, estimate the radius of the ball when the temperature is 3000K...
