A 920-G Empty Iron Kettle Is Put on a Stove $15.0 ^ { \circ } \mathrm { C } \text { to } 93.0 ^ { \circ } \mathrm { C } \text { ? }$

A 920-g empty iron kettle is put on a stove. How much heat in joules must it absorb to raise its temperature form $15.0 ^ { \circ } \mathrm { C } \text { to } 93.0 ^ { \circ } \mathrm { C } \text { ? }$ The specific heat for iron is $113 \mathrm { cal } / \mathrm { kg } \cdot \mathrm { C } ^ { \circ }$ and 1 cal=4.186 J

A) 40,500 J
B) 40,100J
C) 33,900 J
D) 8110 J
