Which mechanism causes reduced heat transfer when water transitions to steam inside an industrial boiler?

💡 Explanation

Nucleate boiling forms an insulating vapor film, therefore conductivity across surfaces reduces because steam has much lower thermal conductivity than liquid water, rather than convective or radiation-driven gains, which are less significant.
