Sounds like Chemistry to me. So our teacher sends us all home with packets full of info on things we've never covered in class and I've got to do this. Here's one problem that I'm not sure if I did right.
What is the specific heat of a metal substance if 135 kJ of heat is needed to raise 5.1 kg of the metal from 20 deg. C to 30 deg. C?
The formula is "heat needed to raise temp" = (mass)(specific heat)(delta temp)
so I made it 135 = (5.1)(x)(10)
and I got 2.65 J/Kgdeg.C for specific heat. Is this correct? Thank you
