Which consequence results when fluid inside a heat pipe undergoes accelerated evaporation?

💡 Explanation

Vapor lock arises because faster evaporation creates expanding vapor bubbles; therefore, it disrupts liquid return via capillary action, rather than maintaining its cooling. This is because expanding bubbles block liquid flow, halting the process.
