Which outcome occurs when a cryogenic fuel tank in a rocket experiences ullage?

💡 Explanation

Propellant stratification dramatically increases boil-off because poor mixing and heat leaks encourage phase separation generating vapor regions; therefore, significant vapor venting results, rather than pressure equalization or efficiency gains in the engine.
