What method did Urey develop that was crucial for the Manhattan Project?
Gaseous Diffusion
Centrifugation
Electrolysis
Thermal Cycling
Answer
Gaseous Diffusion, the method developed by Harold Urey, played a pivotal role in the Manhattan Project. This technique allowed for the separation of uranium isotopes by utilizing the slight difference in their diffusion rates through a porous barrier. The process enriched uranium-235, the fissile isotope necessary for creating the atomic bomb, thereby making it a critical step in the successful development of this devastating weapon.
