Boiling point varies with
Direct Answer
Option C: exerted pressure
Vapour pressure is intrinsically linked to temperature. As exerted pressure increases, the energy required for molecules to escape the liquid phase rises, thereby elevating the boiling point. This fundamental thermodynamic principle is critical for managing LNG fuel tank pressures and preventing uncontrolled boil-off under the IGF Code safety framework.
