A tanker is loaded with 5,000 barrels of petroleum. The cargo was loaded at a temperature of 70°F, and the coefficient of expansion is .0004. What is the net amount in barrels of cargo loaded?

Correct Answer: Option B — 4980

Standard petroleum measurement requires correcting volume for temperature variations. Since standard volume is measured at $60^\circ\text{F}$, loading at $70^\circ\text{F}$ means the cargo contracts upon cooling to standard: $5,000 - (5,000 \times 0.0004 \times 10) = 4,980$ net barrels per ASTM volume correction standards.
