Compared with a small pan of the same metal, a pan of five times the mass has a heat capacity that is:
AFive times greater
BFive times smaller
CExactly the same size
DTwenty-five times more
Answer & Solution
Correct answer: A. Five times greater
1. Heat capacity scales with the amount of material present.
2. The heat capacity of the large pan is five times greater than that of the small pan.
3. Both are made of the same material, but the mass of the large pan is five times greater.
4. The larger amount of material requires a proportionally larger amount of energy to yield the same temperature change.
