The heterogeneous form of this process usually occurs at grain boundaries and is faster than the homogenous form at similar conditions, and this process is usually divided into four regimes, the first of which is called incubation.
The Zeldovich equation gives the kinetics of an early stage of this process. Heat flux dramatically decreases during liquid-vapor transitions when the heat transfer mechanism changes from this type of boiling to film boiling. The heterogeneous form of this process usually occurs at grain boundaries and is faster than the homogenous form at similar conditions, and this process is usually divided into four regimes, the first of which is called incubation. This process usually occurs after the free energy for the formation of new volume reaches its maximum, and this process sees the creation of tiny spherical particles that propagate to grow larger particles. For 10 points, identify this process which is exemplified by the formation of bubbles in soda and is the basis for cloud seeding.
The Zeldovich equation gives the kinetics of an early stage of this process.
