So there is a question on our review guide and im not surewhere to start, heres the question: A piece of iron and a piece of copper, each with a mass of10.0g and the initial temperature of 23 degrees C, are each heatedto 150 degrees C. how much heat is required for each piece ofmetal? I know there is an equation for this question im just not surewhich one to use..... if any one could help i would appreciateit.

Explanation / Answer

For the piece of iron, heat = mass * specific heat * temperature difference        = 10.0 g * 0.449J/g•C * ( 150 - 23)        = 570.23 J For the piece of copper, heat = 10.0 g * 0.385 J/g•C * (150 -23)        = 488.95 J
