a 500 g piece of iron changes 7 degrees when heat is added. How much hear energy produced this change in temp?

Homework Answers

Answer #1

heat absorbed by the piece of iron = m * Cp * dt

                                                    = 500g * 0.444 J /g oC * 7 oC

                                                   = 1554 J

specific heat capacity of iron = 0.444 J /g oC (refer to your text book)
