Final answer:
The amount of liquid to load into a tank depends on both the legal weight limits and the amount the liquid will expand in transit.
Step-by-step explanation:
The amount of liquid to load into a tank depends on both the legal weight limits and the amount the liquid will expand in transit. When a liquid is transported, it can expand or contract due to changes in temperature, which can affect the overall volume of the liquid. Additionally, legal weight limits may restrict the maximum amount of liquid that can be loaded into a tank to ensure safe transportation.
