Answer
4320KJ
Work Step by Step
q= m* Cp * Delta T
q= 400g * .24 J/g0C * 45 0C
the formula is in the work and the:
CP: specific heat
m: mass
Delta T: change in temperature
you then plug everything into the equation and then you are done. you get the mass and temp change from the problem and you look up the specific heat. your teacher will either tell you to memorize it or they will give it to you.
