Vapor pressure in cargo tanks is affected by:
Direct Answer
Option C: temperature of cargo
Vapor pressure within a cargo tank is directly proportional to the temperature of the stored petroleum product. As cargo temperature increases, molecular kinetic energy rises, accelerating evaporation and significantly increasing tank pressure, which requires careful monitoring via ISGOTT guidelines.
