I have this problem: How much heat energy is required to raise the temperature of 0.365kg of copper from 23.0 ∘C to 60.0 ∘C? The specific heat of copper is 0.0920 cal/(g⋅∘C).
I did the equation using formula Heat= mass x change in temperature x specific heat.
I got the answer 1211.824 but it's showing up wrong for some reason. I think it's the rounding or significant figure count? Can someone please help me out?
Thanks

  1. If I multiply 365 x 0.0920 x 37 I obtain 1242.46 J which I would round to 1.24E3. I think you punched in the wrong digits AND didn't round properly.
