Specific heat and heat capacity

Level 1

It needs 17.92 17.92 kJ of heat energy to increase the temperature of an iron ball from 1 0 ∘ C 10^\circ \text{C} to 3 0 ∘ C 30^\circ \text{C} . If the mass of the iron ball is 2 2 kg, what are the specific heat and heat capacity, respectively, of the iron ball?

A: 448.0 J/kg ⋅ ∘ C \cdot ^{\circ}\text{C} \quad B: 0.896 J/ ∘ C ^{\circ}\text{C} A: 0.448 J/kg ⋅ ∘ C \cdot ^{\circ}\text{C} \quad B: 0.896 J/ ∘ C ^{\circ}\text{C} A: 448.0 J/kg ⋅ ∘ C \cdot ^{\circ}\text{C} \quad B: 896.0 J/ ∘ C ^{\circ}\text{C} A: 224.0 J/kg ⋅ ∘ C \cdot ^{\circ}\text{C} \quad B: 448.0 J/ ∘ C ^{\circ}\text{C}
