Concept:Heat capacity is the total heat needed to raise an entire object's temperature by 1 K.Explanation:The heat added is $Q = C\Delta T$, where $C$ is heat capacity.Since the temperature rise is $1\,\text{K}$, we get $Q = C \times 1 = C$.Therefore, the heat required for the whole 10 kg copper sample is its heat capacity.Specific heat capacity would be the heat needed per unit mass, not for the entire 10 kg object.Answer:C. heat capacity
