An electric current heats a 225 g copper wire from 20.0 °C to 40.0 °C. How much heat was generated by the electric current? (ccopper = 0.093 cal/gm-deg)

  • physical science -

    M*C*(change in T)=
    225*.093*20 = ___ calories

    This assumes that none of the heat was lost to the surroundings
