Question 1 of 2066636ee728f7522a1c51760f

A cargo of oil has a coefficient of expansion of .0005 per degree F. If this cargo is loaded at 70°F, and a cargo temperature of 90°F is expected at the discharge port, how many barrels would you expect to unload if you loaded 10,000 barrels?

🔍 Key Concepts

• Coefficient of thermal expansion and what it means for volume change • How to calculate change in temperature (ΔT) in degrees Fahrenheit • How to apply a percentage (fractional) change to an original volume of cargo

💭 Think About

• First, determine how many degrees the temperature will change between loading and discharge. Is it getting warmer or cooler? • Next, think about whether the cargo volume should increase or decrease when the temperature rises, given a positive coefficient of expansion. • Then, figure out how much of the original 10,000 barrels that volume change represents. How do you turn the coefficient and temperature change into a single multiplier to apply to 10,000?

✅ Before You Answer

• Verify you correctly computed ΔT = discharge temperature − loading temperature. • Confirm that you multiply the coefficient of expansion × ΔT to get the fractional change in volume. • Check that you apply the fractional change to 10,000 barrels in the right direction (increase vs decrease) before choosing the closest answer choice.
