Question

A company that manufactures cookware has conducted numerous trials to see which metal needs the least amount of energy (measured in Joules, J) to be raised to high temperatures, and records the averages in a table.


Which claim will this company most likely make?

Aluminum pans are the most energy-efficient cookware.
Copper pans are the most energy-efficient cookware, but they cost the most.
Iron pans require less energy to heat up than copper frying pans, but they cost less.
Copper pans require the most energy to heat up.

Answer 1

"Copper pans are the most energy-efficient cookware, but they cost the most."

Reason: the table shows copper requires the least Joules to reach high temperatures (lowest energy input), so copper is most energy-efficient; copper is also typically the most expensive of the listed metals.
