Which outcome results when a constant heat flux is applied to a material undergoing solid-liquid phase transition?

💡 Explanation

When constant heat flux is applied during a solid-liquid phase transition, the latent heat is absorbed, driving phase change at a constant rate because the temperature remains constant at the melting point. Therefore an advancing interface at constant speed results, rather than increased thermal gradients, decreased latent heat, or uniform distribution, which require differing conditions.
