ThermoChemistry: Enthalpy
« on: May 11, 2010, 09:07:29 AM »
How much will the temperature change if 3000kj of thermal energy is removed from a 12.50kj peice of iron, and the specific heat of iron is 450j/kg degrees celcius. Any help would be appreciated.

are you sure it's not 12.50 kg of iron?
all you need to do is use q = m x c x delta T to calculate this
