Technician B is correct. Hydrostatic pressure is the pressure exerted by a fluid at rest due to gravity. The pressure in a tank will not change as the liquid cools unless there is a change in the volume of the liquid due to a change in its state (e.g. from liquid to solid). However, the containment system must be designed to withstand the changing pressures created as the liquid changes states.
