medium · Enhanced ACT science
Four metal samples of equal mass are heated, and the temperature rise from the same amount of added heat is recorded: aluminum = 11°C, iron = 24°C, copper = 27°C, lead = 79°C.
Which sample required the most heat to raise its temperature by 1°C?
- Aluminum, which showed the smallest temperature rise of the four
- Lead, because it had the largest recorded temperature increase
- Copper, which had a temperature rise between iron and lead
- Iron, which fell in the middle of the recorded values
