A subcritical state will result by flattening a critical mass of fissionable material into the shape of a hamburger.
To find the answer, we need to know about the critical mass.
<h3>What is critical mass?</h3>
A material's nuclear characteristics (particularly, its nuclear fission cross-section), density, shape, enrichment, purity, temperature, and environment all affect its critical mass.
A mass of fissile material is considered to be in a critical state when a nuclear chain reaction in the mass is self-sustaining and there is no change in power, temperature, or neutron population.
At a specific temperature, a mass might be precisely critical.
A subcritical state will result by flattening a critical mass of fissionable material into the shape of a hamburger.
The cross sections for fission and absorption grow as the relative neutron velocity drops.
Thus, we can conclude that, a subcritical state will result by flattening a critical mass of fissionable material into the shape of a hamburger.
