Answer options
- AHow quickly the tank drains while it is unloaded
- BSpace left for the liquid to expand with heat Correct

A liquid takes up more room as its temperature rises, so a cargo tank is never loaded to the very top. The unfilled space set aside for that expansion is what tanker drivers call outage.
