Simplified Measurement Verification Practice Test

When a vessel used as a measure must stay accurate across temperature changes, we look at how much its volume can expand and still be considered correct. For a vehicle tank used as a standard measure, standards set a specific expansive percentage to account for both the liquid and the tank material expanding with heat. That value is 0.75 percent. This means the tank’s capacity may vary up to 0.75 percent with temperature without compromising its role as a standard. The other options are not the standard allowances used in practice, so 0.75 percent is chosen as the appropriate balance between accuracy and practicality.
