Why does the iron bench feel hotter than the wooden one under the same sunlight? The answer lies in specific heat capacity:
Both benches receive the same heat energy.
Iron has a lower specific heat capacity than wood.
With the same energy, iron’s temperature rises more quickly.
Higher temperature → more heat transfer to the hand.
Result: iron feels hotter than wood.
The exam trap: don’t just write “iron absorbs more heat.” The key clue is lower specific heat capacity.
AHA! Lower capacity, higher heat. Not by sight, but by INSIGHT!
