Question

AN iron bar of mass 869g cools from 94 degrees C to 5 degrees C. Calculate the heat released (in kJ) by the metal.

Answer 1

Use heat capacity found here: http://www.engineeringtoolbox.com/specific-heat-metals-d_152.html

Answer 2

Along with the formula
q = C ΔT = C ( Tf - Ti )
where q is amount of heat, C is heat capacity

Answer 3

Make sense?

Answer 4

Be sure to use consistent units with the heat capacity you choose.
