When 90 kJ is removed from a 2-kg copper bar its temperature drops from 200 degrees Celsius to 85 degrees Celsius what is the specific heat of the iron?
q( Joules) = mass grams * specific heat * change in temperature 90 kj = 90000 Joules 2 kg = 2000 grams 90000 Joules = (2000 g)( SP )(200 C - 80 C) 90000 = 240000(SP) 0.375 J/gC ( The actual specific heat of copper is 0.385 J/gC, so close enough for the problem type )
